Question On Conversations

So in a conversation I made, I want to remove someone from the convo. (Don't worry, that person is fine with it). The convo is at it's person limit, one person no longer cares to be in the convo, and a new one wants to join.

It's not possible to kick someone from a convo, they need to leave themselves. Which is fine, they want to leave so they can remove themselves.

HOWEVER, the convo does not appear in their convo list. They say they went through their convos and dont see the one in question.

I'd prefer not to make a new convo, so is it possible to either
a) force kick someone
b) make the convo show up again for them

Are either of these possible?

 

@colin350 he can help

 

Use discord noob

 

I use discord. But I use the convos to host DnD campaigns. Every time we tried using discord for that, it proves to be a horrible platform
