First time decarbing

I've done Hella research, and I am confident that I will be able to do it without much smell if any, but I want to make sure I have the steps right first. Due to where I live, it's illegal, and I don't wan to get in trouble.

I am planning on decarbing 1/2 oz of bud, in one (or multiple, depending) Mason jars. I am also going to wrap it in foil as I heard that reduces smell also. I will be doing it outside in our breville air fryer (which also has an oven/convection oven setting) - needs cleaned anyway so it just gives me an excuse to clean it out)

I've seen different temperatures/times, as I have looked online and YouTube videos on it, I wrote notes on a video I saw, and the temperature was 225⁰F, and the time was 50 minutes. I can turn the convection function off, but I may forget, so, not sure if 225 is a good temp, and I'm pretty sure 50 minutes would probably burn it.

I've seen people saying Mason jars and air fryers but haven't really seen much on it other than putting it in an air fryer in a Mason jar.

I won't be doing this until the house is empty for the majority of the day, so I have a few days before doing this. Thanks in advance for any advice or help yall have!

Tldr: trying to decarb in my air fryer/oven in a Mason jar as scent free as possible.
