Unwanted Deck Cloud App notifications

I decided to try out using my ecloud account today. After a few hours I began getting notifications from the Deck murenacloud app. I have never used this app.

Is this normal?
Can I disable this app somehow or is it just part of the cloud account?

In the meantime I have deleted the account on my phone (S9+) to avoid receiving the notifications.

Thank you for any advice.
