How to allow apps to take screenshots in wayland when denied first time?

I used to use flameshot in my Fedora on Wayland(Gnome). When i first launched it via "flameshot gui" the system asked whether i allow flameshot to take screenshots or something like that i clicked yes and everything worked. This time when i installed fedora, flameshot and launched it i accidentally clicked "Esc" and the prompt was closed. So i tried launching it again, but no prompt was showed again, instead i only see this error.

$ flameshot gui

flameshot: error: Unable to capture screen
flameshot: error: Unable to capture screen
flameshot: info: Screenshot aborted.

How can i allow flameshot to take screenshots again? I tried reinstalling the app, but it didn't work. I can theoretically reinstall the whole OS, but that just seem a bit of an overkill.
