Open page (or modal) covering whole viewport

Hi! For a productivity app, I want to open a page or modal, which will cover the whole viewport.
This means removing botom smartphone 2-3 buttons navigations.

How can I do that?

Hi, you can open a page in a modal by changing the “Open page in modal” selection in the Open page flow function to True.

Thank you! That was quite easy. Still don’t know how to cover the whole viewport, even smartphone bottom buttons
