Can't find an option to add a LINE account with GroupConnect in Marketing Cloud.
The account dropdown in blank. How to add account?
Currently going through this myself. To activate Line, you'll have to go through your Account Exec. Seems that it is something that requires backend configuration. Updates when we get it set up.
You need to create a provider in Line app and that will be visible here under the account. Let me know u need any more details on this.
