Can't detect secret passage in "Season of Bloom"

[Sveroboi]

The season of bloom level ("other world") wrecks my nerves anyway. But now I am almost there, but I fail to detect the secret passage near the end. I looked it up on youtube videos where it is but none of my characters can see it. Has it to do with the magic lantern? Or do I fail the perception check? I am pretty much stuck in the game now as I defended the capital first, and now I can't even get other characters for this level or gear up in the capital or so.

What secret passage are you talking about? Do you have a screenshot or share the link of the video?

As far as i know, no secret passage in that area is link to progression.

There are no secret passages in Lamashtu's Womb, only the transporting fog banks. While you wear the lantern, you are not transported, while you are not, you are. You can just keep the lantern on after meeting the gnome and move on. At last you come to a fog bank with wall behind it. There you take off the lantern and are transported to the flower.
I leave out the sequence with the bird, assuming you know it - if not, it can be googled easily enough.

In womb of lamashtu, you have a plane A and when you cross a fog without the lantern, besides being teleported, you reach the plane B. You must explore everything in both planes.

I admit I didn't find the bird puzzle by myself, but it is easy to find on Google

I found out on my own but before I used walkthroughs and there was some talk about a secret passage. For example in this video in 10:39 https://www.youtube.com/watch?v=bPdibsHw348&t=648s they go through a secret door near the eastern edge of the map. This door doesn't get highlighted for me, maybe very high perception check.
But I found out you don't need that place to get along.

The secret passage to simply to more loot, not a required quest. Were you looking for road signs saying "SECRET PASSAGE THIS WAY!"

The perception check system and inability to try again is Pathfinder (and valid criticism), not the game devs. Well, II guess you could blame the devs for trying to stay true to the rules.
