Using dictation in textedit object with Voice Control (MacOS Catalina)

Hi i'm trying to use dictation speech recognition inside Max. I developed the patch in Mojave and there Speech-to-Text works fine but now i have to switch to Catalina unfortunately.

When i use Voice Control to dictate i can work offline (what i need) and use it in apps like Safari and TextEdit.app but inside Max with a textedit object open it doesn't work. Voice Control itself works in Max (if i create a manual command in the Accessibilty of the System Prefs in the Voice Control panel, for instance to open a Finder Item by a voice command) but i don't get the spoken text inside Max to use it.

Does someone knows a way to achieve this? I tried already a lot of ways but without any luck...
Here are (hopefully) some usefull things which could lead to a solution:
- In the Security and Privacy of the System Prefs in the Speech Recognition panel there is no Max. Is there a way to get access and set Max in the list (if it will be helpfull of course). Or maybe make a Max standalone app where you put something like <key>NSSpeechRecognitionUsageDescription</key> <string>allow speech recognition</string> <true/> Info.plist file? Like you had to do to make the first standalones for Catalina. I did some attempts without success.
- I read something about that Voice Control only supports NSControl based inputs.


Hereby the patch which worked fine for me offline in Mojave

Thanks in advance!
