Send an emal by someone else

[WebPortal]

I'm building a flow that sends an email (V2).

Now, it should not be sent by me (the flow creator) but by another account.

I understand I should get that other person's permission, but how?

 You need permission for send email form another user's mailbox ,

Then you can set "From(Send as)" to the email you want to be From. 

The connection you use should have "Send As" Permission for the email you set in "From(Send As)"
