Confirm visa details

You are correct. You do not need any kind of visa because you will be covered by 24 hour visa free transit. All you have to do is to walk from one gate to the other and you will not be a subject of immigration and customs inspection during the process. You will just encounter a security check between the two gates. Also, you do not need to fill out any forms and also you do not need to perform any formality.

The only detail that slightly worries me is just 1 hour of transit time... Very, very tight, I have to admit. Hopefully, your incoming flight will be on time. Otherwise, in case of a missing flight the airline will have to take care of you in terms of substitute flight. Even in that case, you will not bear any consequences because this is not your fault and you will be covered by visa free scheme.
