does anyone know which license I need for executing bot channels registration? I followed folling tutorial and my license (O365 Business Basic) is not sufficient: https://learn.microsoft.com/de-de/azure/bot-service/bot-service-quickstart-registration?view=azure-bot-service-4.0
Upon the link you provided in the question, I am not sure which channel would you like to add, and the link just describing how to create a bot service in azure portal. This action just need a subscription in your tenant so that you can pay for your bot service.
If I misunderstood your mean, pls offer more details, thx.

You can create an account for free.
If you haven't got a subscription, you'll see this page when visit bot service:
If you don't get a correct subscription, you may see error message when creating bot:
