Rage question involving a concentration tagged ability

[Taunka]

In our game we have a barbarian with the free archetype sorcerer bloodline. He casts flame dancer which has a concentration tag and has a duration of 1 minute. He casts this on himself then goes into his rage. We have said that it is kosher because it has a duration and not a sustain action tied to it, but we were curious if this was a correct ruling or not would love to hear opinions

It is 100% correct by RAW.

We figured that was correct. Thanks for letting me know being a new GM I'm trying to learn as much as I can in understanding RAW as possible thanks for a quick response!
