Describe the bug
I'm trying the new electron version, 5.0. Has new Chromium, Node 12 and V8 engine.
https://electronjs.org/blog/electron-5-0

To Reproduce
Steps to reproduce the behaviour:

1. Remove yarn.lock file to generate a new one
2. Change electron version on package.json to 5.0.0
3. Build the snap package and install it
4. Run it on from a terminal, it will crash and show this message:

julian@mypc:~/Code/teams-for-linux$ teams-for-linux 
[31893:0502/075604.540153: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 /snap/teams-for-linux/x1/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap (core dumped)

Expected behavior
It should run with no issues

Desktop (please complete the following information):

• OS: Ubuntu 18.04/1904
• Installation package snap
• Version 0.2.1

Additional context
Build on .deb works with no issues

we should not be in electron 5.0.0. Drop back to 4.x.x.

There are many changes in node12 that affect the spellchecker and other libraries, so worth waiting until is more stable.
