Brown Scapular Rosary Obligation

[JMKC]

I know that one of the obligations of wearing the Brown Scapular is to pray the rosary daily. Today, however, I heard that the full rosary is actually all three (traditionally) or four mysteries (i.e. 15-20 decades). With that said, is the obligation for the Brown scapular only to pray 5 decades or all 15/20 a day?

Thanks in advance

This website says you only have to say 5 decades a day.

That’s what I understand, and what I do. A (5) decade mystery daily.
