ApiKeyScheme was deprecated, in version 5 you can use like this:

services.AddSwaggerGen(c =>
  {
    c.SwaggerDoc("v1", new Info { Title = "You api title", Version = "v1" });
    c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
      {
        Description = @"JWT Authorization header using the Bearer scheme. \r\n\r\n 
                      Enter 'Bearer' [space] and then your token in the text input below.
                      \r\n\r\nExample: 'Bearer 12345abcdef'",
         Name = "Authorization",
         In = ParameterLocation.Header,
         Type = SecuritySchemeType.ApiKey,
         Scheme = "Bearer"
       });

    c.AddSecurityRequirement(new OpenApiSecurityRequirement()
      {
        {
          new OpenApiSecurityScheme
          {
            Reference = new OpenApiReference
              {
                Type = ReferenceType.SecurityScheme,
                Id = "Bearer"
              },
              Scheme = "oauth2",
              Name = "Bearer",
              In = ParameterLocation.Header,

            },
            new List()
          }
        });
    var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
    var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
    c.IncludeXmlComments(xmlPath);
});
