Azure Function did not get triggered after being published to the portal

Question

Hi,

I was following this official guide (link below) to publish my azure blob trigger function to the azure portal.
https://learn.microsoft.com/en-us/azure/azure-functions/functions-develop-vs?tabs=in-process#publish-to-azure
The publishing process is succeed and I was able to see my function in the portal. However, the problem is, when I tried to change a file inside the monitored Azure Container, it did not trigger the function like it would when my function was still runs locally.

I've also checked inside the Application Insight for logs but it still empty, further confirming that my function did not get triggered at all.
Is there any other steps I need to be checked for my function to be run properly,
Sincerelly,

Guruh.
