There is a bundle in the p2 repository(e.g. https://download.eclipse.org/releases/2023-06 ) that doesn't belong to any feature, how do I install it ?
As far as I can tell, I can't install it through p2 because the things p2 manages directly are features. In other words, I can't install it through the following interface:

All I can do is download this bundle separately and put it in the dropnins directory to use it.
Is there any other way? Thanks.
