ChatUI - I can't see the avatar with the ChatUI extension

Good evening, I can't view avatars with ChatUI.
I inserted an avatar in png format of 100x100 pixels but nothing to do, the avatar cannot be seen.
How can I solve it?
The rest works ok for now.
Thanks Marco.

Can you send a screen recording, a screenshot of your blocks, and/or the AIA file?

do you mean this exension?

or maybe you are intresting with this:

here are the blocks that include ChatUI

I think the container that holds the chat UI or the avatar, it's size might change. Sending the AIA would be appreciated, but try setting the containers that hold the objects to a set number in pixels or a percentage and stop using "automatic" or "fill parent". Maybe this will work idk
