CSM at 40's (I will not promote)

After a check up of my competencies with CharGPT, it turns out I'm a good fit for a position in Customer Success, or Onboarding. As I'm driven by people and satisfaction. I'm a digital native. Entrepreneur and tech enthusiast. But I'm almost 40's and never really work in a startup environment. The closest was a VR production company I founded, where we work in a agile and scrum workflow. What advices can you give me to get a job in such a position ? Can I share a resume to have an exterior perspective then mine and LLM ?
