AspNetCore 3.1下使用Swagger 5.0授权问题

依赖包：
netcoreapp3.1
IdentityModel 4.1.1
Swashbuckle.AspNetCore 5.0.0
Microsoft.AspNetCore.Authentication.JwtBearer 3.1.1

登录是依赖于IdentityServer4。
客户端是API项目，使用了.NET Core 3.1，安装了Swagger做接口ui。
如下为API项目的Startup.cs文件内容：

    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddRepoExtentions(Configuration);
            services.AddControllers();
            services.AddAuthentication("Bearer")
                .AddJwtBearer("Bearer", options =>
                {
                    options.Authority = "https://localhost:5001";
                    options.RequireHttpsMetadata = false;

                    options.Audience = "api1";
                });
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" }); 
                var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
                var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
                c.IncludeXmlComments(xmlPath,true); //添加控制器层注释（true表示显示控制器注释）
                
                c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
                {
                    Description = "JWT授权(数据将在请求头中进行传输) 直接在下框中输入Bearer {token}（注意两者之间是一个空格）"",
                    Name = "Authorization",
                    In = ParameterLocation.Header,
                    Type = SecuritySchemeType.ApiKey,
                    BearerFormat = "JWT",
                    Scheme = "Bearer"
                });

                c.AddSecurityRequirement(new OpenApiSecurityRequirement()
                {
                    {
                        new OpenApiSecurityScheme
                        {
                            Reference = new OpenApiReference {
                                Type = ReferenceType.SecurityScheme,
                                Id = "Bearer"
                            }
                        },
                        new string[] { }
                    }
                });
            });
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseHttpsRedirection();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();
            
            app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
            });
            app.UseEndpoints(endpoints => { endpoints.MapControllers(); });
        }
    }

其中xml备注需要单独开启如下配置：
