How to use the"Hide in Queue"plugin?

[create]

Excuse me.
I installed the “Hide in Queue"plugin. But I still can’t find the tags like"Hide in Queue”“Remove from Queue” “No Hierarchy”.
For example:

And I have no custom css to disturb.
So，I can’t use the"Hide in Queue"plugin.

Could someone please tell me how to use this plugin?
Thank you very much.

You have to use the omnibar ctr+/ or the slash menu / to apply powerup tags e.g., type in /hide in queue and press enter or click the option.
