Building Eventhub connection string with KeyVault secret

I am trying to create an Azure Function App which is an EventHub Trigger. The thing is that to connect to Azure Eventhub, I don't have the full connection string. Instead I have the Eventhub SAS token stored as secret in a Key Vault.

I would like to know if in the App Settings section there is a way to build the connection string by passing that token that I get from the key vault.

I have a variable KEYVAULT_SAS_SECRET whose value I want to use in another variable within the App Setting.

enter image description here

Would it be possible to reference the KEYVAULT_SAS_SECRET variable to construct the connection string that is stored in a second variable?

Something like this:

Endpoint=sb://some-namespace.servicebus.windows.net/;SharedAccessKeyName=policy;SharedAccessKey=[KEYVAULT_SAS_SECRET];EntityPath=eventhub-topic.

Thank you very much in advance

Unfortunately it is not possible to reference Azure Function App Settings variable in another App Settings variables.

In your particular case you have to construct EventHub connection string from two App Settings variables directly in your code
