Deploying to AppServicePlan Functions from Azure Pipelines takes a long time

Question

I'm deploying my application to Azure Functions using the pipeline below.
Deploying to Functions in the Consumption plan completes the deployment stage in less than a minute, but deploying to Functions in the App Service Plan takes more than 10 minutes to deploy.

Why is it taking so long to deploy to Functions in AppServicePlan from Azure Pipelines?
