Click the Connect button from the Connections widget. Once the Connect button is clicked, the API Key popup will open as in the second image.

Note: Only a card admin or an account admin in Brex can connect Brex with Quolum. If you are not either a card admin or account admin in Brex, you can invite him/her to make a connection.
