How to zoom/scale RDP session on Android?

Hi everyone, I have a question about RDM on Android.

My RDP session looks very small on my phone, especially the Windows UI, icons, and text.
I have already tried changing the resolution/display settings, but the size still looks the same.

I'm looking for a way to scale/zoom the entire RDP session proportionally, for example to 125%, 150%, or 200%.

I don't mean Windows Magnifier or a zoom that follows the mouse/cursor.

Does RDM for Android have a setting or gesture for this type of RDP viewport scaling/zoom?

I've attached screenshots showing how the RDP session currently looks on my phone.
Thanks! 🙏
