Hello, I'm from Portugal and I'm having trouble adding the payment methods MBWAY and Multibanco to the footer of my online store. I've tried watching YouTube videos, but I'm still unable to insert the codes into my store even after attempting to use the script provided in the video.

My store is using the Warehouse 2.4.7 theme. If anyone knows how to add these payment methods, please send me the code or provide a clear explanation. Thank you.
