Embebed app URL requests

[JuanGrasso]

Hello everybody, im developing an app and i have the following question:
Where can i config the endpoint which  the embebed app make the GET request when a merchant access to the app from the store panel:

Currently it make the GET req to the redirect_uri that is set during the OAuth flow.
I want to maintain the redirect_uri during the app installation but i would like to modify the endpoint where the embebed app make the request.

Is that possible? 

Thanks you very much!
