I pretty much copied Shane Youngs cart app (https://www.youtube.com/watch?v=Ztn39KuOW0g) - "Power Apps Shopping Cart new for 2021" then modified it for my use.
App works well, and the data collection however I am having the issue of joining the data together as a complete order.
The cart ordered items contains multiple entries attached to an OrderID eg,

Then the other list collects the personal information relating to the cart order with an ID that matches the OrderID

The plan was to use Automate to grab all the info when an order is placed, join it together and present the personal information with a list below of the ordered items.
I watched another video (https://www.youtube.com/watch?v=kiSYLjAcVVE) - "Power Automate - Multiple SharePoint Lists and Report" and was able to get some kind of result for a single item, but not the whole cart list and I can't figure it out.

End result I am wanting to send an email that shows the complete order, per order with all details.
Any ideas?
