Announcements via Bluetooth during a workout

Hello everyone,
I have downloaded a training plan for a half marathon to my watch via Garmin Connect.
During the individual training sessions, I always get announcements on my headphones, such as "Running - 10 minutes in heart rate zone 2" - I think that's good.
Unfortunately, I also always get heart rate warnings "Heart rate high" or "Heart rate low" or "Heart rate in range" - I would like to deactivate these.
Does anyone know how to do this?
I've already tried everything - I can deactivate the segment announcements, but not the HR warnings.
The settings in the "Running" app don't seem to have any influence.

  • These alerts are about your HR not being in the range expected for the workout. As HR lags, and then drifts, it happens often during workouts with an HR goal.

    There is no way to disable these alerts.

    Put up with the alerts and try to keep a steady effort (pace on flat and running power otherwise) during your runs. Pick an effort that gets your HR within range within a couple of minutes max.

    Alternatively, use a plan based on pace and/or replace the planned workout by a workout you build in Connect with a target or running power range corresponding to the HR zone you want.
