Create an agreement from a library template and send for signature - this action does not send email

Create an agreement from a library template and send for signature - this action in power automate does NOT send email even though it runs successfully returning Agreement ID and I am able to see the agreements that are sent to the participants under Manage --> Waiting for you 

I am currently taken a trail subscription for testing purpose could this be a reason I hope not but what could be the possible root cause. Please assist.
