Ticktick installed from snapcraft not showing icon in window switcher

I installed Ticktick from snapcraft. The icon is visible on activities overview, but not on the window switcher, it just shows a generic icon there.

I had this problem with other app, but it was appimage; and to fix it I just downloaded the icon and pointed to it’s location in the .desktop file. However, with snap apps I don’t know how can I modify icon.

I’m on Fedora 40.
