Momentum 7.0 coverpage: Only five navigation buttons allowed?

I am in the process of revamping my 4yo SS Momentum website. I currently have 5 navigation link buttons on my home page designed from a cover page (www.belasphoto.com). How do I add more buttons? If I go to my Home page in Pages and hover over any of the 5 buttons, I can click "edit action", which brings up a left column list of the 5 navigation buttons on the cover page and their settings. I see no way to add an additional one, nor do I see a way to delete a current action.

If you have a minute, please post where to look to add or delete navigation action buttons on a Momentum cover page. Thanks.

On the SS Help Center, it says that the Momentum cover page has up to five navigation links. I guess this is hardwired into this template.

Are there any work-arounds to add more? Plugins? Code inserts?

If you use a Business Plan or higher, we can add code to add more navigation buttons.

You can share link to cover page, we can help easier

My coverpage url is: https://www.belasphoto.com/. I'm on the business plan.
