As someone else pointed out, the M1/M2 MacBook Airs & 13" MacBook Pros do not support more than one external display natively. That is not related to the cable but is just the capability of the MacBooks.
You can use more than one display with DisplayLink technology. I think that Dell used to use USB docks that had DisplayLink but I don't think the WD19 uses it so if that is the case then you will not be able to use more than one display.
