InventoryNotice usage on Experimental

Heya folks,

I've seen some use of rust.InventoryNotice on a few legacy plugins and wondered if that functionality was still around for experimental? If not, is there anything like it that I can use to display a brief notification on the screen?

I see in the assembly there's Notices, NoticeArea and ItemPickupNotice, though I haven't had any luck using any of them thus far.

 

I'll hold tight for now then and just use chat messages. Thanks!
