Multi-region API Management Deployment

Hi

We wish to deploy Azure API Management in internal VNet mode (within a VNet and Subnet) and this will be a Multi-region deployment. We're deploying it through Bicep code. The only relevant official MS guidance I could find is here--> https://video2.skills-academy.com/en-us/azure/api-management/api-management-howto-deploy-multi-region

Understand that there's

1. How do we specify the resource group for the APIM in secondary region?
2. What should be set as the fqdn and domainNameLabel settings for the Public IP resource created in the secondary region?
3. Is this all we need to configure to get the multi-region APIM deployment or are there any other considerations like SSL certificate availability in secondary region:

      additionalLocations: [
            {
              disableGateway: bool
              location: 'string'
              natGatewayState: 'string'
              publicIpAddressId: 'string'
              sku: {
                capacity: int
                name: 'string'
              }
              virtualNetworkConfiguration: {
                subnetResourceId: 'string'
              }
              zones: [
                'string'
              ]
            }
          ]
   

Any relevant articles / blogs that detail the process of APIM multi-region deployment?

Thanks
