Good day, thanks for your question. I am glad to provide assistance to you today. If this was previously available on a lower version of Edge Canary then something might have happened when a newer version was released. In this case, if you still remember the version on which it was still there then you can download it from the link below.

It is also highly encouraged to send a feedback to the Edge team regarding this matter and you can cascade it from the browser by going to 3 dots or 3 lines > Help and feedback.
