"Unpublish" button not showing on "Site Pages" library where "Approve/Reject" Flow configured

Hi,

I have SharePoint "Site Pages" Library where Site Pages or News Posts are getting created. I have configured "Power Automate Flow" for Approval/Reject for selected item/page. Earlier I used to get "Unpublish" button on clicking on "More" option for selected item. But recently I am not getting this option instead getting as "Send for Approval or Cancel Approval".

How can I enable "Unpublish" button again keeping Power Automate intact ? Or is this default behavior of functionality in SharePoint Online If so is there any documentation available ?

Regards,

Pratik
