How can I make the internal SSD disk visible on Mac desktop?

Hi, group.

I believe this is an issue asked many times before, but I really didn't find any satisfactory answer browsing the community files.

So, as I was working on OS Catalina and, now, on OS Sequoia, I see all my external drives on the desktop, BUT NOT the internal ssd hard drive.

What can I do to solve this issue, for me to browse, for instance, the Apps folder, like before.

Thanks a lot for any invaluable help!

Best regards
