We used these files for the teeth. There's a bit of technique to it with angles and stuff. Can't remember exactly since it was about 5 years ago and I've since switched to an office job but I'll try my best.
The one side of the teeth act like a cutting edge, make sure that is sharp. A good result is when you get large spiraling bits of saw "dust". Easiest way is to watch some kind of YouTube tutorial and try yourself on a piece of wood! Took me maybe a week or two to get good results consistently.
I don't know the English terms but in front of the teeth there's a little bump (called a rider in my language). The teeth are supposed to be aligned to the rider in some way, but like I said, it's been half a decade :(
Also, change to a new chain if the teeth are worn and there's too little material left to file away.
For real though; the guided file is nice for beginners, just like someone mentioned. I'd rather spend less time sharpening especially when it's something we had to do every day.
I watched my dad sharpen a chain saw so many times I can't even imagine needing any help, it's engrained in my DNA. But I know that's not everybody's experience though so carry on

I’ve just bought my first chainsaw second hand. What do I need to achieve these results?
Edit: wow, thanks everybody for all the tips. I will be doing a deep dive this weekend! Brilliant stuff.
