Uninstall "dependencies"

Hello everyone. I am new to snaps.
While installing an app, several dependencies are installed. Example: when I installed firefox, following were installed:
core18 20200427 1754 latest/stable canonical✓ base
firefox 76.0-2 355 latest/stable mozilla✓ -
gnome-3-28-1804 3.28.0-16-g27c9498.27c9498 116 latest/stable canonical✓ -
gtk-common-themes 0.1-36-gc75f853 1506 latest/stable canonical✓ -
snapd 2.44.3 7264 latest/stable canonical✓ snapd

When I want to uninstall, is there a way to cleanup the dependencies not needed anymore?
Is there something like “sudo apt autoremove”?
