On a new deployment of PAM, 3rd party services cannot be configured. After going to the Configuration page, the 3rd Party page is blank and there is no plus sign to expand as with Symantec Modules.
If the license is not applied, most features within the GUI are not enabled. This includes the 3rd Party configuration page.
To apply a license, follow the instructions in the Install a New License section of the Licensing and Product Usage documentation page.
Once the license has been applied, 3rd Party configurations are now enabled.
If a license has not been supplied yet, refer to KB195856 - How to Create a PAM License Request for more information.
