Open documents in Office Online instead of desktop application

Hi,

We are using M-Files Web Client (vNext) with a vault hosted in M-Files Cloud.
CO-Authoring is enabled and the Microsoft 365 integration is configured.

When opening Office documents (Word / Excel / PowerPoint) from the Web Client, the files are opened in the desktop applications instead of Office Online (Office for the web).

Question:

  • How can we ensure that documents are opened in Office Online rather than the desktop applications?

Thanks in advance.
