How do we make a custom MFE a course page?

We would like to make a custom MFE a course page like Discussions. How can this be done?

I found this link as one possible solution. Is this still relevant for an MFE?

I’ll answer the second question regarding the course tabs custom page: that simply creates an old-school static page in the LMS, not the MFE. The link will appear in the course tabs navigation in the MFE and the LMS.

I’ll let someone more knowledgeable answer your first question.
