Synthesize stakeholder Interviews

I am new to UX, and working on my first project.

I have completed Business stakeholders interviews to understand business and project goals.

Stakeholders involved:

Could someone please tell me how to synthesize stakeholder interview? And share the template to present insights of stakeholder interview finding?

I need to present it to the stakeholders about the vision and shared project goals of the project.

Once they okay that, I will start user interview.

Thanks in advance!!
