Art creator apps that include your char?

I really want to add a background to my story that is like a social media platform, however I don’t know of any good apps to do so. I discovered a template to edit but I do not know how to add my char into it. If anyone could help, that would be great. Thank you. :grin:

Thank you but how would I add my character into it?

(never got this notification)
you would do this.
&overlay NAME create
&overlay NAME opacity 1 in 0
&overlay NAME moves to layer #
&CHAR moves to layer #
or you can ask someone to make you a social media overlay with your character already in it
