How many and what resources to keep in the ARM template

Hi,

We are working on creating a custom connector to ingest the data in Azure Sentinel. We want to add resources in the azure deploy JSON template file. We are taking reference of SentinelOne data connector for the same. However, we are stuck at one point, wherein we are not getting How many and what resources to keep in the azuredeploy ARM template (https://github.com/Azure/Azure-Sentinel/blob/master/DataConnectors/SentinelOne/azuredeploy_Connector_SentinelOneAPI_AzureFunction.json).

Can someone please help me determine how many and what resources to keep in the azuredeploy json file for a custom connector (azuredeploy_DataConnector_API_AzureFunctionApp_template.json)?
