What will happen if I try to fix no access error by removing the Homebridge UI and reinstalling it?
### Current Situation

When updating a plugin, I get an error message I have not seen before:

The user "homebridge" does not have write access to the target directory:

/usr/local/lib/node_modules

I see that a tip is to remove the Homebridge UI and reinstalling, using two terminal commands:

# cleanup
sudo npm uninstall -g homebridge-config-ui-x

# reinstall
sudo npm install -g --unsafe-perm homebridge-config-ui-x

Being very scared of messing up my Homebridge system, what do these commands do? Is there any risk of causing any serious issues to my system? It sounds scary to uninstall Homebridge...
