App configurations - I am unable to add the lookup values in the app configurations in the iframe

Could you kindly elaborate on what you're trying to do? Because you reference both iframe and fetching configs directly it's not entirely clear what your end goal is.

I guess you may mix up the development part (how develeopers have to implement that feature into their app) and the management part (how the MDM detects that to provide oyu the possibility to set the values for the provided parameters by the app).

And be aware that the app must have it included, you can't just manage any app.

Apologies for the confusion,

1. I’m trying to implement app-managed configurations in my EMM portal, but I’m being redirected to the iframe-managed config where I can’t input lookup values. I can only add configuration values in the iframe, but it only allows a single value at a time.

2.I want to display these managed configurations directly in my EMM portal UI, so I can add lookup values and revisit them later to make changes.
