Airdrop Notifications persistant on iMac - can not find setting

Hello,

I frequently airdrop items (Photos, documents) from my iPhone to my iMac (24" M1 2021, MacOS 14.4.1) and the airdrop notifications persist until I cancel them using the "X". If I remember correctly. they used to just disappear after a minute or two, or there was a setting to do so. I can not find that setting.

I've looking on the notification itself, I've check the notification settings in system settings but there are no options for airdrop or finder.

Thanks for the help.
