SQL Server 2014 Create DDL trigger on Create Table that creates a trigger for the table - sql-server

Question

I'm working with a third party tool that creates databases and tables. I would like a trigger on one of those tables being created. I thought I would try to create a server DDL trigger that fires when the table is created in a new database, which in turn creates a trigger on that table. I cannot add the trigger to the 'model' database because this table is created via the tool dynamically.
I've tried the following:
CREATE TRIGGER ddl_trig_createTable
ON ALL SERVER
FOR CREATE_TABLE
AS
DECLARE #databaseName varchar(255)
DECLARE #AffectedTables varchar(255)
SELECT #AffectedTables = EVENTDATA().value('(/EVENT_INSTANCE/ObjectName)[1]','nvarchar(100)')
IF (#AffectedTables IN ('DynamicallyCreatedTable'))
BEGIN
select #databaseName = CAST(eventdata().query('/EVENT_INSTANCE/DatabaseName[1]/text()') as NVarchar(128))
EXEC('CREATE TRIGGER ' + #databaseName + '.[dbo].[tgrDynamicTableTrigger]
ON
' + #databaseName + '.[dbo].[DynamicallyCreatedTable]
AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON
-- trigger code here
END')
END
GO
Which produces the following error when the table is created;
Msg 166, Level 15, State 1, Line 1 'CREATE/ALTER TRIGGER' does not
allow specifying the database name as a prefix to the object name.
I tried changing the dynamic sql by replacing the fully qualified table name to attempt a 'use' statement:
--- 8< ---
EXEC('use ' + #databaseName + '
CREATE TRIGGER [dbo].[tgrDynamicTableTrigger]
ON
--- 8< ---
However, that produced the following error when the table was created:
Msg 111, Level 15, State 1, Line 2 'CREATE TRIGGER' must be the first
statement in a query batch.
Any ideas?
I'm using SQL Server 2014.

I believe that I have figured it out, thanks mostly to this answer.
Here's the code:
CREATE TRIGGER ddl_trig_createTable
ON ALL SERVER
FOR CREATE_TABLE
AS
DECLARE #statement nvarchar(max) = 'CREATE TRIGGER [dbo].[tgrDynamicTableTrigger]
ON
[dbo].[DynamicallyCreatedTable]
AFTER UPDATE
AS
BEGIN
-- trigger code here
END'
DECLARE #databaseName varchar(255)
DECLARE #AffectedTables varchar(255)
SELECT #AffectedTables = EVENTDATA().value('(/EVENT_INSTANCE/ObjectName)[1]','nvarchar(100)')
IF (#AffectedTables IN ('DynamicallyCreatedTable'))
BEGIN
SET #databaseName = CAST(eventdata().query('/EVENT_INSTANCE/DatabaseName[1]/text()') as NVarchar(128))
DECLARE #sql NVARCHAR(MAX) = QUOTENAME(#databaseName) + '.sys.sp_executesql';
EXEC #sql #statement;
END
GO
