It exists, but it’s been a pretty terrible experience every time I’ve tried it (roughly once every 12-15 months since ~2011). GSuite has some occasional issues arising from connectivity issues, but these also happen to Office365, and are at least as bad (often worse) than in Google Docs and Sheets (I almost never use PowerPoint or Slides, so maybe things are different there.)

Office 365 with onedrive is much nicer than SharePoint IMO.
