Filter certain files from activity log

Like already requested in https://github.com/nextcloud/activity/issues/44, I am also in a need to exclude a certain file from the activity log.
Reason:
I have a tool which periodically uploads an ics file which I then import into Nextcloud. Those uplaods all are shown in the activity log.

Steps to reproduce

1. Use a tool to periodically upload a file via WebDAV.
2. Check the Activity Log.

Expected behaviour

A way to exclude certain files from Activity Log.

Actual behaviour

Activity Log is bloated with unneeded log entries.

The issue does not name a file or test. Start by reviewing the related issue #44 and tracing how WebDAV uploads become Activity Log entries in this app. Define how users identify files to exclude, implement the filtering behavior, and verify that excluded uploads no longer create activity entries while other events remain visible.
