That’s unfortunate, you can set focus modes from shortcuts on ios.
When i turn on my Bluetooth speaker in the shower room it goes into a focus mode that diverts all calls for 15 mins and resumes my podcasts. I thought the experience on macos was supposed to be a superset of the ios one. Really poor decision by apple then.
Shortcuts on iPadOS and whatever beta of Monterey I'm running on this computer can both set and clear focus modes. I use that on my iPad to set a focus mode, which also updates my home screens, and launch AudioBus in one go by running my shortcut. Weirdly it can't check what the current focus mode is.
