Custom Cursor for Blinking Cursor Typewriter Console effect?

[Son25461389nxhx]

Hello!

I am using the new Blinking Curosor Typewriter Console effect but would like to create a custom blinking cursor. I'm trying to mimick the interface of ChatGPT when it replies to a prompt. The cursor in that reference is more of a large blinking rectangle. Any help would be greatly appreciated.

Looking for this. I can see that you can "edit" the cursor shape but from there you can just add a new name but nowhere to customize your new cursor shape...
