Adobe system administrator rights

Hello, I would like to ask for guidance regarding our company’s Adobe account. Our previous Adobe system administrator is no longer working for our company, and as a result, we currently do not have access to manage our subscriptions or agreements. I am unable to renew or make any changes to our company’s Adobe licenses. Is it somehow possible to regain administrative access or transfer admin rights so we can continue managing our subscriptions? Thank you in advance for your help.
