Resize elements

I’m creating an app. The Front-End of the App’s Pages on Thunkable are amazing, but when I download the App to different models of iOS and Android cellphones, the layout gets ugly.

The classic platform has the option to adjust the elements concerning the Relative Size of the Screen (Label, Button…).

How can I do this on ThunkableX?

It’s not possible in the newer drag and drop interface which is very limiting at the moment.
