Trados TTS - Using the Plug-In

I appreciate I asked about using this a few days ago. SDL TTS (text-to-speech) appears to be similar to Word Aloud in Word which reads the text aloud, by converting text to speech, a helpful tool when proofreading translation files in Trados.

After taking advice from RWS Support, I have obtained the API key. Upon attempting to use TTS when working on any SDL Trados Studio file (which I appreciate has to be done in conjunction with Microsoft Azure), the box in the attached screenshot appears.

The box shows my source and target languages (French - France and UK English) as unsupported for the purposes of running TTS. The dropdown boxes for supported source and target languages are empty so I cannot add French - France and UK English as supported by TTS.

I run SDL Trados Studio 2022.  

Does anyone use the SDL TTS plug-in and do you have any thoughts on resolving the problem please, so as to run Trados TTS when working on Trados files?

Many thanks for your help. 

Best wishes,
