I have started using Office 365 recently. I liked the features of Site Pages where we can add Hero Webparts, Highlighted Content webparts etc.

However, I am struggling to apply my custom master page to these site pages. Is that restricted by Microsoft or I am missing any settings?

Kindly guide me here. I can successfully apply the master page to my publishing pages (site/sitename/Pages/).

Custom master pages are currently not supported for "modern" pages.
