Sole proprietor, do I need to keep physical reciepts?

I started my sole proprietor a bit longer than a month ago, so lots of accounting things that I'm still unsure of.
I'm using Freee for bookkeeping, I record my transations there, add the T number (when applicable) in the comments of transactions, take a picture of the reciepts, and organize those pictures by date.

My understanding was that recently (this year?) businesses can opt to keep digital record of the reciepts rather than physical ones. Still have to comply with the 7 years recording keeping rule tho.

I talked to a friend couple days ago, he said that I still have to keep the physical reciepts that I get. And that the above rule only works for reciepts that were digitally issued.

Could anyone confirm which one is correct? I'm now pretty confused about it, specially that I no longer have the physical copies for expenses worth around 100k
