Authenticate Blazor WebAssembly using multiple identity providers

I am learning Blazor WebAssembly and building a small project to be hosted as Static Web App in Azure.

The target framework is net5.0.

When the user clicks over 'login' hyperlink or button, a new page will display the names of some identity providers (Microsoft, Google, SackOverflow, etc.). Then the user will select one to log in.

I did it using just one identity provider (just Microsoft, just Google, etc.).

How can I use multiple identity providers in the same app ?

Someone can help me, please ?
