Get the administrator role for some users on rstudio connect


I am currently experiencing the following problem on my Rstudio Connect environment:
In the past, we used our last name to authenticate.
Recently, we have been using SAML authentication and we use our VISA number.
So we currently have two accounts :

  • an account identified by the family name
  • an account identified by the VISA number

The problem is that I used to be an administrator, but since the authentication change, my new account does not have the administrator role.

I would like to change the status of my current account (identified by my VISA) to administrator, but since I no longer have access to my old administrator account (identified by my last name), I don't know how to proceed.

Can you please help me?
