I have a ASP.NET Web Api 2 application. I added Swashbuckle to it (Swagger for .NET). It displays my endpoints no problem, but in order to send a request I need to attach an

I think it's not a good way to send the authorization header by modifying index.html. You can only add some settings to achieve that.
Here is my solution:
1.Add settings in Starup.cs ConfigureServices method

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddSwaggerGen(config => {
            config.SwaggerDoc("v1", new OpenApiInfo() { Title = "WebAPI", Version = "v1" });
            config.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
            {
                Name = "Authorization",
                In = ParameterLocation.Header,
                Type = SecuritySchemeType.ApiKey,
                Scheme = "Bearer"
            });
            config.AddSecurityRequirement(new OpenApiSecurityRequirement
            {
                {
                    new OpenApiSecurityScheme
                    {
                        Reference = new OpenApiReference
                        {
                            Type = ReferenceType.SecurityScheme,
                            Id = "Bearer"
                        }
                    },
                    Array.Empty()
                }
            });
        });
    }

2.Add settings in Startup.cs Configure method

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        app.UseSwagger();
        app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "API Document"));
    }

After add settings, then run this project, you can find an Authorization button swagger page, and you can use it to set the authorization header.
