Elementor form & Mollie?

Hello, my name is Mark Salden and I am a freelance graphic designer from Belgium. I am building a website for a client using Elementor in WordPress, and the client would like to include a “become a member” form. This form should contain the usual fields such as first name, last name, etc., as well as an option to select a membership type, with each type having its own price. After the user makes a selection and clicks “submit”, they should be able to pay for the chosen membership immediately, preferably via Bancontact, Visa… (Options like Stripe or PayPal are less commonly used here in Belgium.) I assume this needs to be connected to Mollie. However, I assume I can’t rely solely on the standard Elementor form widget for this, right? Would Contact Form 7 required as extra plugin? Something else? Is this possible? And if so, are there any tutorials available? I hope someone can point me in the right direction. Thanks in advance! Kind regards, Mark
