Try adding a screen to display the values of your records. I found a suggested solution of how to loop through the elements and add to a text template for the screen here. With a link to an image displaying the steps here.

The trick here is getting the other non-Id values out of the sObject
Collection, and to do that, you'll need a loop. Where it gets really
hairy is getting it laid out correctly. I haven't built this yet, it's
entirely theoretical, but here's what I would attempt.
First, make a new variable (we'll call it varDisplayText) to hold all
of your text.
Then, in your loop, pass the Collection to a standard sObject
Variable.
From there, use an Assignment element to Add (not equals!) the first
value of the first column to varDisplayText.
Then (and I think you can do this in the same Assignment element, I am
pretty sure it will do it in order), use varDisplayText again but
instead of using Equals, use Add, and add the text string ", ".
Add another line in the same element (or a new Assignment element if
necessary), use varDisplayText again, with Add, then the first value
in your second column.
Add another line in the same element (or a new Assignment element if
necessary), use varDisplayText again, with Add, then the comma text
string again, but with a line break character afterwards.
Point back to your loop so you can get the next set of values in your
collection.
When the flow runs, it should do the Assignment with the add, which
functions as concatenation, for each row, creating a different row of
text.
I am REALLY not certain this would work, but it's what I would try; it
works on paper. Otherwise, I think you're limited to a VF page here.
