I am trying to test something. I already have an IG account set up with a chatbot, and I want to add another IG account. I am assigned as admin to that other account (it doesn’t have any Facebook page linked, it’s just the IG account), and I have access to it thru Meta Business Suite, but for some reason when I try to add it to Manychat, it doesn’t show up.

I already tried doing what was explained here and here, without luck.
