How to check if the collection is selected in outliner?

Question

How to check if a collection is selected or not in the outliner using Python?

Here I've selected the following collections: "scene 1", "scene 2" and "scene 3".

As far as I know, there is no direct way to check if certain collections are selected. You can only check what the name of the currently selected collection is using:

bpy.context.collection.name

and you can check what the actively selected collection is:

import bpy
for collection in bpy.data.collections:
    if collection == bpy.context.view_layer.active_layer_collection.collection:
        print(collection.name)
