The problem was not in my code, but on the platform on which I posted it.
I sent dev.wechat.com (English version of the developer platform), even if the documents look / have been updated to this day, there is no SDK for iOS and Android. And your presentation will never be considered (5 months after there are no signs of activity in the materials yet).
Decision:
Create an account on the Chinese version of the developer platform ( open.weixin.qq.com , then send your application to it. These are exactly the same fields and order as the English platform. Google translate will be your best friend here.
I received my application after three business days.
