Unable to send email from particular sender address

Question

Hi Team, I hope this message finds you well. We are currently facing an issue with verifying our custom domain in Azure Communication Service. Specifically, we are unable to add the required TXT record in our domain registrar, as the option to do so is unavailable. As a result, we are unable to verify the custom domain and use our team email address for sending emails via the service. We attempted to use the Azure-managed domain as an alternative; however, we encountered difficulties in setting the sender email address, as the default sender address is different from our intended team email address. Could you kindly provide guidance or a workaround that would enable us to send emails using our team email address with Azure Communication Service, despite these limitations?
