Now we need to set up the "remote control" to your most used apps:
Open the Shortcuts app again
Create a new shortcut
Search for "Open App"
Once it appears in the search results, click on it
You should see something like "Open" "App"
Click on "App" and select the app you want to open
You can then rename the shortcut and, if you want, change the icon and color
Click "Done" in the top right corner
Repeat for up to a maximum of 7 apps
Create a new shortcut in the Shortcuts app
Search for "Get Current Focus" and select it
Then search for "Set Focus" and set it to turn off
Optionally, add an "if" condition to prevent error pop-ups when no focus mode is active. This will show a less intrusive notification instead.
Rename the shortcut to "End Focus" and add an icon and color if you want
Click "Done" in the top right corner
