Recovering files from SSD of MacBook Pro that won’t boot due to water damage

Before you start lecturing me on making backups, I'm happy no announce that 90% of my data is backed up. I did exclude some non-essential folders because my internet is garbage. Losing these are an inconvenience at most. I have not opened my MacBook yet, still looking at what my options are before I start something I will regret. I simply want to connect the old SSD to a new MacBook once to copy some files. I have no interest in keeping the SSD after that. I'm a bit lost because browsing google is mainly providing me with recovery services (a bit overkill? SSD should be intact) and products intended for converting the SSD into some kind of permanent external drive, but I'm only interested in a single copy. Fancy casings are not needed. It has also come to my attention that regular SSD adapters might not work because apple used a proprietary design. Is this true? I don't have the old MacBook with me so I'm not 100% sure what model it is. I think it's a 2015 MacBook Pro (no touch bar). What type of connector do I need? I'm sorry if this is a bit vague. Thank you in advance.
