Nextcloud client not shown in notitication senders Windows 10

Hi everybody,

 i actually have a problem on one laptop that has Win10 Pro 1903 installed.

For some strange reasons, this PC doens’t show any Nextcloud notification. I checked into computer settings and i found that Nextcloud is not listed into notification senders.

I’m struggling with this kind of problem but i haven’t found any solution (i also updated nextcloud client and Win10 without success).

Thank you in advence for yout patience!
