startAt in animation mixer

I added the following code to the editor but it shows that there is no startAt parameter. Did I miss something on setup?

model.setAttribute('animation-mixer', {

        clip: '*1',

        // crossFadeDuration: 0.02,

        startAt: 2500,

      })

Are you using A-Frame or Studio?
