Accessing keys and values in nested object with VBA - arrays

Question

I use the translation API from Deepl in VBA. My request is working pretty fine and returns some translated html-text. However, I am not able to get the "text"-value in the returned object:
So my request looks as follows:
Set objHTTP = CreateObject("MSXML2.ServerXMLHTTP")
url = api & "?" & authKey & "&" & targetLng & "&" & tagHandling & "&" & sourceLng
Debug.Print url
objHTTP.Open "POST", url, False
objHTTP.setRequestHeader "Host", "api-free.deepl.com"
objHTTP.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
objHTTP.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
objHTTP.setRequestHeader "Accept", "*/*"
objHTTP.send "text=" & text
textResponse = objHTTP.responseText 'textResponse is defined as String
Debug.Print textResponse
I get the following output:
{
"translations":
[
{"detected_source_language":"DE",
"text":"<h2>SizeI</h2>love \"Paperwhite\".<br><br><img
src=\"https://ws-eu.amazon-adsystem.com/widgets/q?_encoding=UTF8"
}
]
}
I further tried:
'get the script control:
Set ScriptEngine = CreateObject("ScriptControl")
ScriptEngine.Language = "JScript"
'Get the string and parse it:
Set jsonObject = ScriptEngine.Eval("(" & textResponse & ")")
jsonObject returns [object Object] and I have no idea how to process this.
How can I access this object and return just the text-value?

Using VBA-JSON from here: https://github.com/VBA-tools/VBA-JSON
Function Test20220318()
Dim json As Object, txt, trans As Collection, t As Object, k
txt = [E1].Value 'using json stored in a cell for testing
Set json = JsonConverter.ParseJson(txt) 'a Dictionary object
Set trans = json("translations") 'access dictionary by key to get collection/array
For Each t In trans 'loop over items in collection/array
For Each k In t 'loop over keys in t
Debug.Print k, "=", t(k) 'print key and associated value
Next
Next t
End Function

The response is a JSON String.
You have to convert the JSON string to an object
Set jsonObject = DecodeJsonString(objHTTP.responseText)
