I am trying generate a token for Instagram Basic Display. But i get the error 400 Session Invalid

I've created a Meta app and got a Whatsapp test number. I can write to it and it is send to the webhook fine. But I'd like to add that number to a group so others can send messages to it as well, without necessarily needing to add that weird number.

When trying to do so it says that Business number can't be added to a group.

Is there something I can do? Am I forced to add my own number to the app and convert it to a Business number?

I'd rather not, I'd like to keep mine personal

FB.ui share is returning a null response to my app after posting done. I can see the href link posted on my feed but the response is null -sharing my snippet FB.ui({ method: 'share', appId: , display: 'popup', quote: , href: },function(response) {console.log(response)}); This has been working for a longtime and has suddenly stopped since the new share dialog on FB has been implemented
Can someone pls help asap.
