Your question is tagged 'powerapps', but in the description you mention 'msflow' (Power Automate). Depending on which product you are talking about, you would approach it differently.

In Power Apps, you can use the function Char(10) to add a new line to a string. So if you have a string variable and a collection with values, you can use something like the expression below:

Set(testString, "A");
Collect(testArray, "B", "C");
Set(result, Concat(testArray, testString & Value & Char(10)))

In Power Automate, it's not as simple, but I've found one alternative at this community post where you can use the expression below to have a new line character:

json('{"NL":"\n"}')?['NL']

So if you have your variables initialized as below:

You can append the new line inside an Apply to each block:

Hope this helps!
