It should be noted that JLPT is not a direct equivalent to CEFR. CEFR requires you to pass speaking and writing, JLPT does not demand you to be able to write, or speak, at all. IT only tests listening and reading. This ironically means that while yeah, you will be able to read a LOT of kanji with JLPT N2, you might not be anywhere near B2 level at speaking and conversation, and probably not at all when it comes to writing (writing Kanji is a whole other thing beyond being able to read, it requires dedicated practice, but anyways a lot of people now don't need to since you can type it out on your phone or computer, and just copy that onto the form or whatever you are writing on)
