[help wanted] firejail profile

I've tried to make a firejail profile for Bootstrap Studio, and it seems to work. However I'm very new to firejail so I'd like someone to review it and fix/enhance if needed (I've copied most options from Chromium profile).

bootstrapstudio.profile:

# Firejail profile for Bootstrap Studio
# Description: A powerful web design tool for creating responsive websites using the Bootstrap framework.
include globals.local

# comment this line for the first launch (network required to register the license key). after the registration close the program and uncomment this line again.
net none

apparmor
caps.keep sys_chroot
netfilter
nodbus
nodvd
nogroups

?BROWSER_DISABLE_U2F: nou2f
shell none
disable-mnt

run as:

firejail --private=/home/$USER/firejail --appimage --profile=bootstrapstudio.profile ./BootstrapStudio_4.5.8.AppImage

(change $USER to your user name, and "/firejail" to desired directory)

Good luck with this request. This is just a user forum for people who need help with using the Bootstrap Studio program. Personally, I have no idea what "Firejail" is, what it does, or what you need it for.
