Please add a way to detect and delete or hide duplicate ics events, only keeping the most current one. I believe this usually happens by checking for duplicate UIDs.

My university provides me with an ICAL link which I added to Proton Calendar. After a while it starts to add duplicate after duplicate to the point where there are like 20+ duplicate events. It becomes unusable and I have to remove and re-add the ICAL link to make it bearable again every once in a while.
