Problem with publication

Question

Hello, I created a resource group named "Prova" on Azure, and within it, I created the language model "CLUMichele." Later, I created a bot using the Bot Framework Composer, which is functional. However, when I tried to publish it, I couldn't insert an existing resource. Therefore, during the publishing process, I created a new resource from the composer within the same resource group. However, when I try to test the bot on Azure using "Test in web chat," the chat doesn't start, or rather, it appears empty, and the bot doesn't work. Note: I have an Azure subscription for students.
