Do Raisin One-Time Passcodes show the amount of money I am depositing?

Currently in Argentina on a long backpacking trip and no longer have my UK SIM. One of my fixed-term savings accounts has matured and I need to reinvest the money. Raisin needs OTPs to make deposits in new accounts, and so I've asked my sister if we can use her number for that (seems legit to me). I'd rather she didn't know how much money I was banking though so here is my very niche question - when you make a deposit in Raisin, do the one time passcodes that she'll receive on my behalf also include tell you the amount of money that I am depositing?

It's a question so niche that the answer isn't anywhere to be found on the internet, but am sure someone on here will know. Thanks!
