List of VLOOKUP items [duplicate]

I have a ledger spreadsheet that contains name of people and sports that they practice, which is organized like this:

column A | column B | column CJohn     | Soccer   | Q1/2021John     | Soccer   | Q2/2021Mary     | Swimming | Q1/2021Mary     | Swimming | Q2/2021Mary     | Swimming | Q3/2021Mary     | Soccer   | Q3/2021Joe      | Soccer   | Q2/2021Joe      | Vaulting | Q2/2021

On a separate sheet, I have the unique list of persons and I want a formula to list the unique set of sports for each person

column A | column BJohn     | SoccerMary     | Swimming, SoccerJoe      | Soccer, Vaulting

With VLOOKUP I can choose the first entry, but I am having trouble google sheets generating the list of all sports as output.
