Hi,
we are creating a flow in Azure AD B2C by using custom policies. By default, access_token contains an audience claim (named aud) which has the value set to the application ID.
We would like to change that value by attaching an additional string to it, ie. aud="applicationID OUR_CUSTOM_ID".
In order to achieve that, we would need to read the aud claim value in the custom policy and then set the aud claim to a new value.
We haven't been successful with neither of those two things, so the questions are:
- how to set a new value to the aud claim for the access token?
- how to read the value of the aud claim from the access token?
Thanks.
