Confusion about door dashing in California

In California, I have a personal auto insurance policy like everyone else with full coverage from Wawanesa. I am interested in door dashing. Wawanesa says they don’t cover ride share. DoorDash has their own insurance that comes into play when I’m actively delivering an order. So if something were to happen when I’m waiting on orders, DoorDash insurance wouldn’t cover that and I would need a different personal insurance policy? And if something happens that door dash insurance DOES cover like whole actively delivering, does my personal insurance need to be notified? Will they automatically be told? Thank you
