How to send an email in same email thread using Power Automate?

Question

I am using SharePoint Online. I have created one list to store the data.

I have created two workflows for automation.

The first flow triggers when a new email arrives on Outlook online and creates a new item in the SharePoint Online list.

Please check the below screenshots for a better understanding.

Send Email

Receive Email On Create List Item

Receive Email On Update List Item

The second flow triggers when a list item is updated in SharePoint Online and sends an email to the user who has sent the email and item created with the first flow.

Everything works as expected but when the item is updated the second flow sends an email to the user who has sent the email and the item created using the first flow. The second flow starts a new email thread instead of sending emails in the same thread,

Below are the Power Automate flows.

Send Email on Update List Item

Can anyone help me with the same?

Thanks

In this flow, you need to get the Message Id of the Reply to email (V3) output, and this is the one to save and use.
