Phonak Target software?

I’m starting the journey of learning how to make adjustments because my audiologist is becoming very frustrating to deal with and I feel they may not have enough experience with the Marvels. I have purchased a Noaklink already and have been wearing M70’s for almost a year. Is there a known online source to obtain the Target software? Or is there someone who would so kind as to share a copy of it?
Any assistance would be greatly appreciated, thank you.
