Get Access Token from Application Registry using script

[Dazler]

Hi,

I am having a little trouble with a script to get a new access token from the Application Registry.  This registry is created from the BeyondTrust Privileged management plugin, so the application registry was created through that.  

I tried to use the information from the below url, but I get the error "ClientType: client is not supported"

The application registry does not have an entity profile and I can't add one.  Here is a screenshot of my registry.

Can anyone help me with this?
