How long to wait for the answer from App store Connect ? What kind of answer ? Email ? And what about tester ? Do I need do something about it ?

I really appreciate your reply. There are tons of documentation and posts to submit an application to App Store. Is not easy to find what is precisely needed. What is the relation between the Bundle ID in "Certificates, Identifiers & Profiles" and Bundle Identifier in Xcode "Target" "Signing & Capabilities" ? Thank you very much.
