Zoho Writer offline/Microsoft Edge

Zoho Writer offline/Microsoft Edge

Hello,

after a few years I'm back to Zoho Docs, using them on a Surface Go and syncing through all my devices (Macs/iPhone/Android phones/etc).

I installed the Zoho Writer plugin for Microsoft Edge browser.
But still can't see the "offline" documents part (that's pretty important for me!)

Is there a way to activate the "offline" docs on Edge or this browser is totally not compatible?
