App Service scale out failed due to not having additional quota

When I attempt to scale out my instances on Azure App Service (Linux) beyond just one instance I get:

"

The scale out operation for the plan 'security-escape-room-app' failed: Operation cannot be completed without additional quota. Additional details - Location: West US Current Limit (PremiumV3 VMs): 2 Current Usage: 1 Amount required for this deployment (PremiumV3 VMs): 3 (Minimum) New Limit that you should request to enable this deployment: 4. Note that if you experience multiple scaling operations failing (in addition to this one) and need to accommodate the aggregate quota requirements of these operations, you will need to request a higher quota limit than the one currently displayed.

"

I tried to search in the Quotas section in Azure console but I cannot find anything related to the specific quota that is holding down this deployment.

Does anyone know which quota I should configure to allow more than one instances on this?
