@Ali121-coder In our case, we targeted the device group.

In the beginning we let it run hourly to get the clients checked and updated as soon as possible. Later we changed it so that it runs every few hours.
Even if you set it to run hourly, remediation will only run in case your clients haven’t updated to the version/s specified in the detection script.

In case the client already updated to the desired version (with PR or manually by the user), this info will be provided in the PR report (you just need to select all columns to be visible).

@TomislavPeharec thank you so much.
