Need token from Adobe sign client support team

Hi,

Im trying to integrate Adobe Sign with SSO to Azure AD.

I need to contact the Adobe Sign client support team to have them generate a Adobe-Sign-verifictaion token. I cant find any way to contact them. When i click the link in the guide, it redirects me to the main supportsite and i cant find any way to contact the Adobe Sign support team. 

From Microsoft guide:

The Adobe Sign Client support team sends you a randomly generated token. For your domain, the token will be like the following: adobe-sign-verification= xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
