Search for an text modules app / or development (text expander)

Hi, I’m looking for or wanted to suggest an app development: a text expander (Typing Hero) in which you can store text modules. If something like this already exists, I would be happy to hear from you. Thank you.

macros? pre filled text selectors? can you make it clearer?

Eg. kboard | F-Droid - Free and Open Source Android App Repository supports defining text snippets
