MAX Transit ProE Router - getting Speedfusion running

I have two sim cards - At-t and T Mobile - I am trying to get them bonded with speed fusion. I have speed fusion set up - I think. However, it is clear that I have never used any data with speedfusion making me think it really isn’t working.

I upgraded to the latest firm ware as suggested in a prior post - but don’t see the eSim option which seems to be needed for this.

Is there a users guide for this? Documentation seems to be hard to locate.
