I think that till now your whole attention was on writing artices and reviews of products. You have raised some Forum threds and there are some responses of some threds but there are no questions and responses related to ask expert section. It means you did not try to contribute i As Expert Section.
It is a cleasr fact in this site that the Forum Section, As Expert Section and the Article Section are opened to all.
So I think there is no need to get permission to contribute in As Expert Section.
You should ask some questions or answers some questios in this section.
I hope better contribution from you like article section.
