AI Expert - ChatBot Issues

The avatar shows “K”, this should ideally show the Profile Pic of teh user, and in absense of the User profile pic show the the default initial, So in case of Aditya it shoudl be A and in case of Khushal it should be K. Also use blue background for the profile initial.

For the AI Studio Logo, if the logo exists use that. For example We do have a logo for MPL AI Expert. So we should see that logo. In case of no logo show aiko image.
