Hello there,
I have created a Model driven app. when an Item is created, I need to send an email to a user and CC to Created By user.
I am using Power Automate. the action I am starting with is

In email body I should display created by(standard column) user display name.

However, I am getting only Created by 'Unique identifier' not the value i.e. display name or email ID

and another column Assigned to is a lookup from 'Users'(standard table) also not getting display name or email.
What should I use. I understand it should be simple. though I am new to Power platform.
Thanks.
