How to run snap installed programs as different users & groups?

Is there something where I can change the user/group id of Snap installed applications? I would like to secure what folders/files they have access to on my machine.

Similar to

sudo -H -u "$USER" -g "$GROUP" /bin/command

or like systemd

[Service]
Type=simple
User=john
Group=admins
ExecStart=/bin/command
TimeoutStartSec=0
RemainAfterExit=yes
