I have absolutely no idea.
Usually this file is made available easily in these kind of apps for noobs (that I am btw) directly in the settings with some kinds of warning or something.
Here I have nothing, this is why I try to understand how it works before using it more extensively.
I asked nostr:npub1xv8mzscll8vvy5rsdw7dcqtd2j268a6yupr6gzqh86f2ulhy9kkqmclk3x in an other note to explain it, hope he will see it.
