I can't download images from Brave and Telegram

Hi guys, I really like DankMaterialShell, it's so great and beautiful.

But, I can't download images from Brave browser and Telegram (it's a messenger). I don't know why, I tried other browser, they did not work, too, but I can use Firefox to download images. However, I want to use my favorite browser, Brave.

My OS is Fedora and I'm using niri.

P.S. When I switch to kde plasma, it's working!
