Cisco Umbrella - Azure Function Pricing

Hey folks,

We're an MSSP with a client who's looking to onboard a Cisco Umbrella device. I'm trying to calculate how much the associated Azure Function application is going to cost. I have no idea how much memory it'll require, execution times, or how many executions are needed [for the Azure function app].

Is there a sizing tool I'm missing somewhere? Is there somewhere our client can pull that information in the Umbrella device?
