Create Unique List Across Columns (Index/Match/If/Countif)

I'm trying to replicate the following, where I had been using the index/match/contif combo in Excel.

Table: Labor (For each employee added to a receipt in our system, a seperate row)

I need to display this data in a Power BI table, in the following format:

1. No duplicate receipt ids (I have them coming from a related table without dups so no big)

2. Return the Name(s) for the given Receipt id, accross the 4 columns.

Here is the Excel Formula that would be in B2 and copied right.

INDEX(Labor!$C:$C,MATCH(0,IF($A1=Labor!$A:$A,COUNTIF($A2:A2,Labor!$C:$C),""),0))

Possible? Need more info?

Thanks in advance.
