Trying to set up payment to my John Lewis credit card

This is my first post, so apologies if this is a boring, done, topic… I looked online but couldn’t get a straight answer:
I try and submit the JL mastercard account and sort code and Monzo doesn’t recognise it.
I do not want a regular payment, I just want to be able to tranfer money from Monzo to my credit card as and when. Any tips would me most welcome!
