Autoexec Service with latest OSMC release

There seems to be a new procedure for automatically executing code when Kodi starts up, the old method of adding the file to the /home/osmc/.kodi/userdata folder does not seem to be valid anymore. But I am not able to follow step 1.4, which says: Navigate to the autoexec add-on in the addonbrowser and enable it:
Settings > Add-ons > My add-ons > Services > Autoexec Service

I can only find a Add-on browser in the Settings menu, perhaps I am missing something here? TIA.

Is equal to Add-on browser on OSMC Skin.
So if you followed step 1.1 to 1.3 you should find your Addon there

Thanks, I was able to enable it. Where does this setting get stored, can this be done by editing a file? I did not see it in the guisettings.xml file in the userdata folder.

Which setting?

Enabling the autoexec service.

Would be in the addons database
