• This is not a feature request (existing functionality does not work, not missing functionality).
  I will request features on forum or via support.
• I've searched and did not find a similar issue.

Describe the bug
Starting the linux desktop app fails.

To Reproduce
Steps to reproduce the behavior:

1. Start the app via CLI or by clicking on the executable AppImage
2. See error n CLI (there is no feedback (error shown) starting via filemanager or start menu):

[7661:0525/193405.281509:FATAL:setuid_sandbox_host.cc(157)] 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_tutanolYDLnT/chrome-sandbox is owned by root and has mode 4755.
Trace/Breakpoint ausgelöst

Btw. the file in /tmp is generated by tutanota on the fly and not there not having started the app. The app is for shure started as normal user.

Expected behavior
App starts.

Screenshots
not possible

Desktop (please complete the following information):

• OS: Linux
• Desktop Environment, if applicable (on Linux): KDE up to date on Debian
