Expected Behavior

Keepassxc minimises into menubar on MacOS when closed or minimised

Current Behavior

Currently closing quits the app entirely and minimising goes to dock instead, with no configurable options

Possible Solution

Add options (similar to on linux with the statustray)

Context

Especially for KeeHTTP, the app needs to be constantly running in the background, but currently it goes against the MacOS design standards by completely quiting the app when the close window button is hit, and it needs to be minimised to the dock to continue running in background.
