Arch and Manjaro users who run Brave see a message that says that "you're using an unsupported command-line flag --no-sandbox". The recommendation in the AUR page of the brave-bin package (and elsewhere) is

sudo sysctl kernel.unprivileged_userns_clone=1
To make it persist after reboot:
echo kernel.unprivileged_userns_clone = 1 | sudo tee /etc/sysctl.d/00-local-userns.conf

I have to admit that I do not fully grasp that. Can anyone explain that in less technical terms? What do Majaro users who use the Brave browser do about that? Thank you in advance.
