Account login Issues

we are experiencing an issue accessing a Zerotier network created for our company. The programmer who set up the network created it under his personal email, so only he can access the configurations of the network. Additionally, there is no documentation available regarding Zerotier or other networks, making it practically impossible to establish a new connection to our server. Is there any possibility of changing the personal email associated with the network we are connected to, to one belonging to our company? I have the network name, ID, and proof of my connection.

I have the same question.
