How to permanently remove Mindfulness app and complication from Apple Watch?

Over the last few days my watch has been bugging me to download Mindfulness from the Apple store.

I do not want Mindfulness.

i got so fed up with it that I downloaded the app and turned off all the alerts but I was left with the complication on the watch face. I do not want this either. I could not find a way to turn it off!

I then deleted the app. But now it’s constantly bugging me to download it!

How do I get rid of this thing for ever please!

Thanks in advance.
