excel – grab only the first record in the Power Query table merge

I am working on a fairly simple power request project and I have run into a retarder. I have a table with a list of customer purchases with customer ID and date of purchase. On the second table, I have a list of all clients.

I want to merge these two tables to create a new table listing all the customers with their FIRST purchase date. At the present time, the resulting table retrieves all purchases and only duplicates customer information for each purchase record. I am in no way an expert in SQL. I therefore hope that there is a way without code to ask Power Query to only grab the oldest match for each record and not all matches.

Thank you everyone!
