is it mandatory to include “originator” to json while sending an adaptive card to outlook via Power Automate

Question

I am working on an adaptive card which has Action.OpenUrl actions in it and I am trying to send the same via Power Automate to Outlook.

The problem is when I send it to myself, the adaptive card is displayed in the email body but when I trigger the same email to my team members, the adaptive card is missing in the email body.

Has anyone faced any similar issue with adaptive cards? has anyone worked on sending adaptive cards to outlook? if yes, is it mandatory to register at https://outlook.office.com/connectors/oam/publish for actionable messages to be sent to Outlook and to add the 'originator' to the JSON.
