SQL Find Executive All Employees Reports To - sql-server

Question

I have found lots of examples to create a employee reporting structure hierarchy. However, I want to take this a little further and for each employee find the executive they report up through whom reports directly to the CEO. Given the following data:
ID FullName HRLevel SupervisorID
----------- -------------------------------------------------- ---------- ------------
1 Pam Beesly CEO NULL
2 Angela Martin SVP 1
3 Kelly Kapoor SVP 1
4 Meredith Palmer SVP 1
5 Phyllis Vance AVP 3
6 Jan Levinson AVP 4
7 Erin Hannon Associate 5
8 Karen Filippelli Intern 5
I would like a list of all employees with an HRLevel of SVP and below to show the SVP level employee they report up to. So it could be their immediate supervisor or it could be 4 levels above them. Also, if an employee reports directly to the CEO I want that employee to be listed as the DepartmentHead.
Here is what I have so far:
;WITH cte_employees (ID, FullName, HRLevel, SupervisorID, SupervisorName) AS
(
SELECT ID
, FullName
, HRLevel
, SupervisorID
, CONVERT(VARCHAR(50), NULL) AS [SupervisorName]
FROM #Employees
WHERE HRLevel = 'SVP'
UNION ALL
SELECT e.ID
, e.FullName
, e.HRLevel
, e.SupervisorID
, c.FullName AS [SupervisorName]
FROM #Employees e
INNER JOIN cte_employees c
ON e.SupervisorID = c.ID
)
SELECT c2.ID
, c2.FullName
, c2.HRLevel
, c2.SupervisorID
, COALESCE(c2.SupervisorName, c2.FullName) AS [DepartmentHead]
FROM cte_employees c2;
Which yields the immediate supervisor, not the SVP DepartmentHead:
ID FullName HRLevel SupervisorID DepartmentHead
----------- -------------------------------------------------- ---------- ------------ --------------------------------------------------
2 Angela Martin SVP 1 Angela Martin
3 Kelly Kapoor SVP 1 Kelly Kapoor
4 Meredith Palmer SVP 1 Meredith Palmer
5 Phyllis Vance AVP 3 Kelly Kapoor
6 Jan Levinson AVP 4 Meredith Palmer
7 Erin Hannon Associate 5 Phyllis Vance
8 Karen Filippelli Intern 5 Phyllis Vance
The only difference in what I am getting and what I want is that Employee IDs 7 and 8 should have a SVP DepartmentHead of Kelly Kapoor.
Here is my dbfiddle showing this in action.

You are vert close:
IF OBJECT_ID('tempdb.dbo.#Employees ', 'U') IS NOT NULL DROP TABLE #Employees;
CREATE TABLE #Employees(ID INT,
FullName VARCHAR(50),
HRLevel VARCHAR(10),
SupervisorID INT)
INSERT INTO #Employees VALUES (1, 'Pam Beesly', 'CEO', NULL)
INSERT INTO #Employees VALUES (2, 'Angela Martin', 'SVP', 1)
INSERT INTO #Employees VALUES (3, 'Kelly Kapoor', 'SVP', 1)
INSERT INTO #Employees VALUES (4, 'Meredith Palmer', 'SVP', 1)
INSERT INTO #Employees VALUES (5, 'Phyllis Vance', 'AVP', 3)
INSERT INTO #Employees VALUES (6, 'Jan Levinson', 'AVP', 4)
INSERT INTO #Employees VALUES (7, 'Erin Hannon', 'Associate', 5)
INSERT INTO #Employees VALUES (8, 'Karen Filippelli', 'Intern', 5)
;WITH cte_employees (ID, FullName, HRLevel, SupervisorID, SupervisorName) AS
(
SELECT ID
, FullName
, HRLevel
, SupervisorID
, FullName AS [SupervisorName]
FROM #Employees
WHERE HRLevel = 'SVP'
UNION ALL
SELECT e.ID
, e.FullName
, e.HRLevel
, e.SupervisorID
, c.SupervisorName AS [SupervisorName]
FROM #Employees e
INNER JOIN cte_employees c
ON e.SupervisorID = c.ID
)
SELECT c2.ID
, c2.FullName
, c2.HRLevel
, c2.SupervisorID
, c2.SupervisorName AS [DepartmentHead]
FROM cte_employees c2;
