When I quit, I was also worried about how to write a 2-week notice letter correctly. The main thing is to be polite, grateful, and clearly state the date of departure. In the letter, you should thank for the experience gained, express your willingness to hand over the work, and avoid negative comments. I used the tips on 2 week notice letters from httрs://jobssite.ca/tips-for-writing-two-weeks-notice-letter/ – there are specific examples and templates. In the end, my boss appreciated my professional approach, and we parted on a good note. This is really important, because you never know where you will cross paths with former colleagues again!
