Hi @FranckBlack, welcome to the Collabora Online forums!

I have a workaround for your issue. You can use the `Send_UNO_Command` with the value `uno:TrackChanges` as a PostMessage to enable Track Changes.

For more details, refer to the [PostMessage API documentation](https://sdk.collaboraonline.com/docs/postmessage_api.html#id5). You can also check out this example implementation: [framed.doc.html](https://github.com/CollaboraOnline/online/blob/master/browser/html/framed.doc.html).

Thanks,  
Darshan
