On-Premise data gateway : Multiple managers

Good Morning everyone,

I have few questions about the managing rights regarding the Datadflows from PBI webservices and the gateway.

I've just joined a new organisation and i will have to manage all previous PBI  dataflows. The managing rights for the gateway was given to one of my colleague which didn't have any competences since he is a "transition" manager from the previous one to me.

Currently the gateway for all web reports are working perfectly but for any news Dataflows or any modifications, i have to pass throught my colleague account. 

Is it possible that we both have the rights on the gateway at the same time ? Or these rights are only available to one manager at a time ?

Thanks in advance
