You have to do that part with the date using the Expression part.
* Click wherever you want it to show and have the box pop out to the right side that shows the Dynamic content and click Expression.
* start typing in the function box FormatDateTime...it will start narrowing down the options and when you see it pop up just below in purple click on it and so you will have just "formatDateTime" in the function box..put in an "(" and then at the type click Dynamic Content so it shows the choices you can select and find your date field and click on it - when you do it will add something similar to body('Get_item')?['Created'] inside your Parenthesis - just depends on what your field is called and what its pulling from on this part.
* after you have clicked on it go up to that box and go to the end of what it added in but before your close parenthesis (that was added automatically when you put the open one and put -- ,'MM/dd/yyy'
* Then click OK -- blue button
After you click Okay it should show up where you added in purple/pink with an fx and then just show formatDateTim… but if you hover of it you will see the full thing you put in.
Let me know if you still have trouble and I can probably do a quick video to show you.
