Customizing size of video feed for duo cam doorbell

I was monitoring my kids playing out front but didn’t care to see the front porch. I tried adjusting the proportions of the video frame but realized it isn’t possible; nor can I select 1 of them to be viewed solo. I figured you could implement the same code as used with groups to select 1 of the cameras in the gallery view to be displayed. I’m not a coder however so those very well may not be compatible calls. Maybe Windows desktop/Google has spoiled me with the split screen feature for the past few years where I assumed long-press and drag a dividing line would allow resizing of windows.
