Vacuum line leak diagnose

[Oscar6790]

I have a 2019 GT and I believe it has a vacuum leak. It's my first time diagnosing a vacuum leak. What should I check for or where should I start.
Thanks in advance

if there is a vacuum leak, best option in my experience, is a vacuum smoke tester. It puts pressurized smoke into the intake and crankcase systems and you look around for the little puff of smoke coming out somewhere.
