Can you guys help me in creating a SOSTAC Planning Framework applied to digital marketing strategy? Related to this:

As a reaction to the current crisis situation and the resulting consumer behaviour of spending increasingly time at home, Apple is thinking about launching a new streaming service specifically for music concerts. The company approaches you as an expert in digital marketing to develop a digital marketing strategy using a structured approach. Please use a strategy process model for developing the new streaming service's digital marketing strategy and apply each stage to the specific case.

Thank You!
