Question Queuing animations on runtime

Hey !
I am planning on an application, where a user can order multiple animation clips in an order they wish.
It does not have a fix number of how many animation clips those will be. They can also switch out animations as they like.

Whats the best approach to go for ?

I was thinking of manipulating the animation controller of the object on runtime, but was really able to figure out a good way to do it.
Else I was thinking about StateMachineBehaviour or just doing it plain by code playing and queueing the clips.
I am more of a beginner when it comes to the unity animation system. But I am willing to read into stuff.

Can you guys give me an idea ?
