Tutorial in app/Walkthrough

Hello,
I am making an app in Ionic 6 and Angular.
I really like the graphics but I have a problem:
the app must be used by users of all ages,
based on external examples I was thinking of making a small tutorial animation that explains what the buttons are for within the app. Anyone have any idea how I can do it or what tools to use to make it?
To better explain what I mean, I leave you an example below.
