How can I create dynamic shadows in Game Maker 2?

I'm a total beginner and yesterday I spent all day trying. The most I managed in the end was to make a silhouette of the character's sprite moving to the opposite side of the main light, but it looks extremely... Simple, without animation, and very unnatural—has anyone implemented dynamic shadows in their top-down games? If so, could you give me some tips? I would greatly appreciate it!
