What happened to small kitchen appliances that mount under the top kitchen cabinets, above the counters?

I see microwaves and an occasional toaster oven, but what about crock pots, air fryers, 2 piece toasters, hot pots . . .

We use our air fryer quite often. I’d like some sort of bracket or shelf that I can mount under the cabinet to sit it on and get it off the counter.

Any ideas?
