If so, please check out the information in the following link, which outlines how to allow or silence notifications from specific apps during a Focus, which may help: Allow or silence notifications for a Focus on iPhone

2. Tap Apps (or tap Choose Apps), then do one of the following:
* Allow specific apps: Tap Allow Notifications From, tap
