Beginner question : responsive frames for prototyping ?

[tropic crater]

Hello guys, i'm a beginner in figma and i'm more of a dev than a designer. Basically, for work, i must do a test session soon for a web phone app that i'm designing and developping, the ux has been valited and stuff but, as i want to make my coworkers test the app on their phone, i try to make my frames responsive to a few phone sizes, to avoid any problem for the test session.

That being said, my question is : Do i need to make other frames/variants for each phone format ? Can i apply a "fill container" option to a frame or a group of frame ? (like one for iphone 15, one for iphone 14, etc) or can i make the whole frame auto-layout or put constraints to make it adapt to any phone size ? I don't know what approach to choose.

Unfortunately i can't post images in here or leak too much on the app due to professionnal reasons but i'll try to explain eveything the best i can

@tropic crater Sorry but the auto layout and fill container settings apply on the things inside the outermost frame.
As of now there is no such option available so that a design fits to the screen on which it is being displayed.

Doesn’t using Presentation frame use fill? I’ve never tried it with phone screens but worth a look; go to Prototype tab , Prototype settings and find Presentation (says Fill next to it). There’s also None which I believe sets Fit. Sorry I don’t have a concrete answer but worth a try to look into.
