You can also share screen shots of your PayPal and bank statements. Just add a cover letter explaining it all. My boyfriend had to do this as a business owner - he was approved
I’m a freelancer and was approved. I sent in my contracts with my clients- I had them add a section stating I can work remotely, I sent invoices, my bank statements (you can send screenshots of PayPal), my portfolio, and social media in relation to work (LinkedIn,etc)

I used google translate to translate the whole document
Just upload the entire file
Permanent address is your Spanish address. There should be another option directly after or in the next page to add another address. That is where you’ll put you UK addresss
