Only Audiences made using Zapier's "Create Audience" Action are listed here. If this dropdown is empty, or if you want to create another Audience, you should create a separate Zap. No need to set up a Trigger for that other Zap. Instead, go to that Zap's Action. Select "LinkedIn Ads" as the App and "Create Audience" as the Event. Manually test that Zap's "Create Audience" Action one time. Then, come back to this Zap, refresh this dropdown, and select the Audience you just created.

Requests can only be made to domains associated by this application.
