Every travel insurance company has a dedicated 24/7 helpline and emergency center to help you in a situation like this. Your travel insurance policy will have all the details. It will tell you which number to call and what procedure to follow in case of a medical emergency or other travel-related problems.
If you buy the policy on BuyAnyInsurance.ae, you will get a copy of your travel insurance policy in your email inbox. You can easily access it from your phone, so you don't need a physical copy of the document to see what you need to do in an emergency.
