Method to detect opening/closing of new submenu

Howdy, I’ve got a pretty simple question…

Is there a way to detect if the submenu shown below is opened or closed yet?

I wasn’t able to find anything on if it was possible or not in my own research, likely because it is so new.

Thanks in advance for the assistance

The GuiService has things for the Emotes Menu but I don’t think there are not many ways to track the Leaderboard and Inventory.

I’m talking about that entire submenu shown in the image. Detecting when the emotes, inventory, and leaderboard are opened are not my concern.

I’m trying to find what it calls in the CoreGui to see if there’s a bindable event we can listen to.

Edit: It’s called the MoreMenu, so if you’re also trying to look look for that.
