Bank connections in other countries via PLAID

Hi there I noticed other software in UK is using PLAID, I just wondered if its an easy API / etc to use for adding other bank connections? I just noticed that many apps don’t integrate with UK banks because open banking is hard or something, but I’m hoping this is the secret! It’s PLAID .com btw. i have absolutely no affiliation I am just using another accounting app to import my transactions (which runs on PLAID) and then my plan is to import to ADAM from there.
