The process is actually cumbersome if your not prepared for it. I always dislike people replying with oh just id, photo, proof of address type of response as its not genuine to the actualities of it.
You will have to provide a bank statement or welcome letter with these 4 things on the same document: Your full name, address, account number, and Dated within the last 3 months. And then you will get a request to upload your ID with a photo taken off of your smartphone. I didnt own a smartphone for the longest time.
