'Enabling authentication in swagger

I created a asp.net core empty project running on .net6. I am coming across an issue when I am trying to enable authentication in swagger. Swagger UI runs as expected, the only issue is whenever I click on the Authorize green button on the swagger UI it will pop up but say Unknown Security definition type and give me two options Authorize and Close. It does not show under Available authorizations Bearer(http,Bearer) and allow me to enter a jwt value. I ran into this article that goes over bearer authentication but it isn't much help for me. Am I missing something in the .AddSwaggerGen()?

enter image description here

builder.Services.AddAuthorization();

builder.Services.AddSwaggerGen(options => 
{
    options.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
    {
        Scheme = "Bearer",
        BearerFormat = "JWT",
        In = ParameterLocation.Header,
        Name = "Authorization",
        Description = "Bearer Authentication with JWT Token",
        Type = SecuritySchemeType.Http
    });
    options.AddSecurityRequirement(new OpenApiSecurityRequirement
    {
        {
            new OpenApiSecurityScheme
            {
                Reference = new OpenApiReference
                {
                    Id = "Bearer",
                    Type = ReferenceType.SecurityScheme
                }
            },
            new List<string>()
        }
    });
});

var app = builder.Build();
app.UseAuthorization();
app.UseAuthentication();

Solution 1:[1]

I think Scheme should be "bearer" (lowercase b)

Scheme = "bearer",

You have used add authorization before defining your security definition. First define security definition & then use add authorization
