AppImage won't start on Debian 10

[kallerosenbaum]

$ ./Specter-0.10.4.AppImage
[24973:1211/152433.008188:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_SpecteHHjwa9/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap

It does work if I run it with ./Specter-0.10.4.AppImage --no-sandbox, but it's hard to understand the security implications of that. Also, its nearly impossible for users to know about the --no-sandbox flag.

This should at least be addressed somehow in the readme.
