Connecting External Lookup Field via Oauth2.0

[UmairHa2]

I read over Adobes documentation on External Lookup Field but don't see any option to connect via oauth2.0 or generate tokens? Tried adding the auth in the headers section too but no luck. 

Has anyone tried this and have a workaround solution? 

I am trying to connect via oauth2.0 to the external lookup field and pull in selection options in the dropdown. 

The data pulled in fine in Postman with oauth2.0 connection.

First of all, a lookup connects to an API - you don't "connect via oauth2.0 to the external lookup field"

Your options here are limited: 

1. connect to the the external API by passing e.g. a API key etc. 
2. make the call from external lookup to Fusion, which then makes the OAuth call to your external API.
