Do Humpback whales use bubbles as a tool?
On a breezy winter day in Hawai‘i, a team of researchers from Whale Trust Maui watched as a group of humpback whales cavorted around their boat. The wind-rippled ocean surface distorted the view through the ocean–air interface, but one whale repeatedly swished its fins at the surface to produce a vortex that flattened the chop, creating a smooth spot where it placed its eye to look up at the scientists. Photographer and researcher Flip Nicklin, having never seen vortices used in this way, dubbed them “whale windows.” At the end of the encounter, the whale used a different method to construct the window—it blew a perfect air ring from its blowhole, much like a smoker puffs a smoke ring,

I think it's well-documented that humpbacks use bubbles to force their prey into a small volume and then eat them. E.g., https://youtu.be/Q8iDcLTD9wQ

For the geckos at my house, my living room lamp is a valuable tool for attracting their dinner.

HOTP... I guess the question boils down to: "can air/air bubbles be a tool?"
Have used hydro-cavitation for many things (many ultrasonic cleaners utilize cavitation) ... so, a whale using bubble cavitation to net prey would be..... I think, using bubbles as a tool...
Oh & this is a very well-known thing, the Shedd Aaquarium opened their "Bubble Net Cafe" when I was a diver there in 1991, & whales using bubbles were already well-researched & pretty much well-known... at least well known enough to name their first cafe for it!

Just my 2 cents but isn't a whale using bubbles similar to a bat using sonar? Or a rabbit turning it's ears and using the air so it can hear something 2 miles away?
