How does the shrinking bubble work?

Title. How does the shrinking bubble upgrade for hidden pentads work? Does it activate automatically? Do I have to press a button?

once you are at 4/5 orbs found the bubble will slowly shrink.
so its not like you find 1 orb on the outer edge, and the border snaps to the next closest one.

it will only work on the last orb, and it slowly shrinks

It activates automatically as soon as you collect 4 out of 5 pentads. It will shrink only for 5 seconds or so.
Compared to playtest it is VEEERY slow, like few times slower it feels like, really hard to see shrinking.
But the strategy of figuring out which side shrinks faster and which doesn't move at all to estimate whereabouts of the last thingy still works. Just harder to see.
UPD. scratch that, my last shrinking was like 30sec or so lmao, i wonder why did i think it was only 5sec.. Shrank to like half of original size with pentad right in the middle.

30 seconds feels way too fast, it has to be closer to around five minutes

But the speed is still very noticeable, since if the last orb is close to one edge, that edge will even start moving back instead of in. That's a pretty telling thing about where it is even without the bubble being too much smaller than the base size.

I find it useful to do another puzzle in the area while the bubble is shrinking. Then when I come back, the bubble is sometimes tiny, at other times it's barely shrunk. It's very slow though--takes minutes to fully shrink.

Clear, thanks everyone.
