Approval Features for Nextcloud 22

Good Day,

While reviewing all apps in nextcloud saw the features Approval (It’s awesome new features for files), after saw this I’m excited to hear more about this app.

Looking forward also for ready to use Digital Signature for Nextcloud.

MORE POWER NEXTCLOUD

Did someone get it working?
As far as I know this only works on NC22 while Libresign for signing documents only works up to NC21 so I don’t know how those 2 can wokr together.

Has someone some hints or howto guide to get the two of 'em setup`

Thanks.
