Wildcard App ID for Developement Provisioning Profile/"No Code Signing Identity Found"

Question

I am invited as a team member to a developer account. I need to send them a demo application via testflight. I checked inside the application ids list and there is no application created for this purpose. I am not able to create one either, since I only have "team member rights". What I can do though, is to download an IOS Team Provisioning Profile of Development type, that is created with the app id: Xcode IOS Wildcard App ID(*). All good and nice, but when I chose from X-Code the team that I am a member of, it tells me that "No Code Signing Identity Found". If I press Fix issue, I get the message "Your account already has a valid certificate" and that I can revoke and request a new one.

What should I do? Is the wildcard provisioning profile a viable option to create an archive? What does it mean that I revoke my signing identity and request a new one? Does the developer account owner need to create a new certificate specifically for me? Or what is I don't understand about it? Is the signing identity related at all to the developer account? Or I will receive a new one automatically? Can anyone explain in a bit more detail, so that I understand properly?

A wildcard simply means that it can apply to any app. If an app doesn't plan to use application specific requirements, like iCloud or inAppPurchases, then a wildcard profile is fine to use for the rest of your apps. In general, there is no need to download new profiles or certificates from develop.apple.com; you can manage them directly from xCode via Preferences>Accounts>View Detail.
