Online savings account proofs

[Buster1]

I have recently opened an online savings account with Xyz as it is the highest rate of interest. They do not send paper statements and would need the evidence to submit for my partner visa financial requirements as 6 months statement would be required. I could print them out but as it is an online account I wouldn’t be able to get the bank to stamp them. Would these not be accepted or will I need to open a different type of account?
