Can't remove Zoho Writer app for chrome

Can't remove Zoho Writer app for chrome

Hello,

I've installed the Zoho Writer app for google chrome and after that I removed it from chrome. So now, it is not appearing in the chrome list of installed apps.

Nevertheless, all Microsoft Word documents in Google Drive are linked with Zoho Writer and there's the Zoho Writer icon before each Word document.

How can I remove the app?

Kind regards
