Custom Open option in File handler for OneDrive web application

Question

Hello,

I have created app (App Registration) in Azure portal to handling the file in OneDrive.

And followed the same steps which is documented in this link. https://learn.microsoft.com/en-us/onedrive/developer/file-handlers/?view=odsp-graph-online#seamless-authentication-with-file-handlers-20

For the past 6 months it was working fine please find the working screenshot below.

But suddenly the open option is missing in the OneDrive web application for the past 20 days. I tried to be created new app but still it same. Please help me on this.

Thanks,

Tamil Selvam
