Debug Outlook Web addin created in Blazor WASM

Question

I'm creating an Outlook Web Addin. Implementation is done in Blazor WASM. The addin is working, well, but I'm not able to debug the addin when it is loaded in Outlook or neither in the browser. It is a Taskpane addin, which is visible on the right side pane in the outlook and browser as well.

I'm using Visual Studio 2022, but breakpoints are not hit in Visaul Studio.

I do not see my code is loaded in the browser, probably the pane is some IFrame os something like that.

Did somebody experience that kind of issue?

Is ther any way how to debug the Blazor Addin code in Visual Studio or in Browser?

Update:

In this repository https://github.com/OfficeDev/Office-Add-in-samples/tree/main/Samples/blazor-add-in/outlook-blazor-add-in is a sample application.

The readme says that debugging is configured and working. The sad thing is that you need Microsoft 365 E5 developer subscription, which is quite expensive. You have to have a Visual Studio subscription. The free developer sandbox what is mentioned there is not available anymore :(
