Azure Pipeline [Azure Functions for container] task appSettings multi parameter

Question

Hello.
I have been developing and deploying .NET 5 Isolated-Process Azure Functions through visual studio 2019.
Copied the value of the Application configuration setting in local.settings.json from the Publish feature in Visual Studio 2019.

Now I want to deploy .NET 5 Isolated-Process Azure Functions via Azure Pipeline.
Below is my yaml file and dockerfile for publishing of Azure Functions.

Looking at the log, it seems that the setting value is not entered properly.

Also, if you set App Settings with Generic Host Configuration in C#, you set it this way, but I wonder if you set and update in the same way in azure pipeline.

In conclusion, how can I write yaml in Azure Pipeline to configure multiple settings as if they were used in Generic Host in C#?
