Variables available to Universal Login Advanced Options prompts

I see when configuring the Advanced Options for the new universal login experience some string templating going on. For example, on the organization page the pageTitle:
Enter your organization | ${clientName}

Where does clientName come from? Where can I see a list of other variables?

We’d like to be able to inject some custom text here depending on the calling application. Wondering if this can be done using Custom Query Parameters? But not sure if those propagate to that level?

Hey @brendon.parker :wave:

The other possible variables for the Universal Login prompts can be found here (depending on which screen is displayed)

I’m not sure if custom query parameters would propagate to that level though :thinking:
