tl;dr How can I customize the default speech of account linking in Dialogflow?
I would like to require sign-in with my Google Assistant ready application.
Following the guide steps in the official documentation I enabled the account linking for my Default Welcome Intent
which asks the user to sign in.
The process works correctly getting the following speech response in Google Assistant showing the account linking card:
It looks like your {app name} account is not linked yet.
I would like to customise the speech response giving additional information about the linking. Is there any way to modify that?
Thank you for your help.
Update
I tried to require account linking at invocation time replacing the textToSpeech
JSON value from PLACEHOLDER_FOR_SIGN_IN
to my custom text, but it does not work.
