Shell themes and icons don't show in gnome tweaks

so I downloaded and installed Tela-icon-theme and orchis-dark shell theme.
and although gnome extension is installed and user theme is active.
I can’t seem to find those newly installed themes in gnome tweaks!
any ideas?

Where did you download them from and how did you install them? FYI, tela-icon-theme is available in the community repo and orchis-theme-git is available in the AUR (Arch User Repository).

User themes can be installed to ~/.themes.
