If NHI/ETs have such advanced technology, couldn’t they then also be able to cloak as everyday objects?

Apologies if this has been asked before, so forgive my search capability failures.

A thought that I’ve had while scrolling through the plethora of Photos and Videos where the object has been found to be a balloon or something similarly mundane.

If there are indeed other beings, who are coming to visit and they have been studying us in various ways, wouldn’t it be entirely plausible that if they have the technology to reach us, whether through space or other dimensions, they would also have the ability to cloak their craft/devices as everyday innocuous objects – such as balloons?

Not trying to say that every mundane object is a cloaked craft, but rather suggesting that could it be a plausible situation where at least some of those things could be disguised craft?

Edit : correct disgusted to disguised… Although the Jellyfish UAP looks sort of disgusting to be fair.
