Connecting to Backendless database


Hi, I am trying to connect to an external database “backendless” but am not sure what to input in the configuration field. I tried to run it as it is but a connection error pops out. Please advise on what needs to be input into the configuration field. Thank you.

According to the article below, the Configuration field is where you add any necessary connection data (ex: user name, password, secret key):
