This is my 3. try to get help for a ASP.NET Core + Swagger + Azure B2C demo project. I am not sending code because this results into this

Has anyone a short demo for me to make a swagger page that has the endpoint "/test" to verify that the authentication with the bearer token worked?

    first you need an anonymous endpoint that allows login and returns a valid token:

    https://learn.microsoft.com/en-us/azure/active-directory-b2c/access-tokens

    you can skip this if you already have a way to get the access token value

    then add token support to swagger

    builder.Services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1", new OpenApiInfo { Title = "Test01", Version = "v1" });
        c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme()
        {
            Name = "Authorization",
            Type = SecuritySchemeType.ApiKey,
            Scheme = "Bearer",
            BearerFormat = "JWT",
            In = ParameterLocation.Header,
            Description = "JWT Authorization header value: Bearer {token}"
        });
        c.AddSecurityRequirement(new OpenApiSecurityRequirement
        {
            {
                new OpenApiSecurityScheme
                {
                     Reference = new OpenApiReference
                     {
                        Type = ReferenceType.SecurityScheme,
                        Id = "Bearer"
                     }
                },
                new string[] {}
             }
        });
    });
    

    in the swagger ui via authorize, you can enter the token header value ("Bearer {token}") using the token the login action returns
