Dear Pawan Vishwakarma,
Good day!!
I understand your concern but since your concern is related to the Power Automate flow, I would like to suggest you post your concern in the Microsoft Power Automate Community - Power Platform Community to get the detailed help from the experts.
Moreover, as per our search I found a related thread in the Power Automate community: Solved: How to get "Form Id" in Power Automate flow? (MS T... - Power Platform Community (microsoft.com), please check it whether it helps you. (If it doesn't help, we apologize and please feel free to post your concern in the Power Automate community for further assistance.)
Apologies for redirecting you to different community as the members in the category posted focus on the users with the Microsoft 365 concern and have limited knowledge on the Power Automate, so to get the fast and better assistance, we have redirected you in the correct path.
Appreciate your patience and understanding. Have a great day!!
Best Regards,
Sophia
