Great!
Now, I understand your scenario.
So you can create an action inside Power Automate (before Common Data Service action) called Initialize Variable. And select the type "String" and type the name of the variable and the value doesn't need to fill.
After your action called "List records", create a new action called "Apply to each". Select and inside the textbox card insert the "results" or "body" (I don't remember).
Now for each result, your workflow will pass inside this action.
Now, create a new action inside "Apply to each" called "Define variable". Select your variable created and insert the value using your column that you want to show.
And finally, inside your Power Virtual Agents Response action, insert the variable value instead of the "Next link" value.
