Disable app recommendation notifications

I am a new user to Nextcloud. So far I am very satisfied with what I have experienced!

However, I am getting more and more annoyed by the messages I receive with the app recommendations for Notes, Social, etc. I get them several times each day on my Windows desktop, in total more than a dozen times so far. I understand their purpose, but one or two such notifications should be more than sufficient.

I could not find a means to disable them – is there any?
