move/resize calendar app with Shortcuts

I have a Shortcut that rearranges some windows using the Mission Control actions:

1. "Find Windows" to find the app by name
2. "Move window" to set it coordinates
3. "Resize window" to set it dimensions

This works perfectly with any app (for example, I can organize "Chrome" perfectly with this), but it doesn't work only with Calendar app.

In fact, the "Find" step works just fine - as I can see the calendar window jumps to focus as the shortcut runs, but the "Move" and "Resize" just doesn't apply to Calendar.

Again, I'm pretty sure the logic is solid since the exact same sequence works if I replace the app name from "Calendar" to "Chrome".

Any ideas?
