Hello khedr
You have to add ManageHelp name in permission records system name field.
  

     public static readonly PermissionRecord ManageHelp = new PermissionRecord { Name = "Admin area. Manage Help Roles", SystemName = "ManageHelp", Category = "Help" };

Because you given Managerhelp permission name in sitemap.

<siteMapNode SystemName="Help" nopResource="Admin.Help" PermissionNames="ManageHelp" IconClass="fa-question-circle">
      <siteMapNode SystemName="Help topics" nopResource="Admin.Help.Topics" url="https://docs.nopcommerce.com?utm_source=admin-panel&amp;utm_medium=menu&amp;utm_campaign=admin-panel"  IconClass="fa-dot-circle-o" OpenUrlInNewTab="true"/>
      <siteMapNode SystemName="Community forums" nopResource="Admin.Help.Forums" url="https://www.nopcommerce.com/boards?utm_source=admin-panel&amp;utm_medium=menu&amp;utm_campaign=admin-panel"  IconClass="fa-dot-circle-o" OpenUrlInNewTab="true"/>
      <siteMapNode SystemName="Premium support services" nopResource="Admin.Help.SupportServices" url="https://www.nopcommerce.com/nopcommerce-premium-support-services?utm_source=admin-panel&amp;utm_medium=menu&amp;utm_campaign=admin-panel"  IconClass="fa-dot-circle-o" OpenUrlInNewTab="true"/>
    </siteMapNode>

issue is solved khedr from the above solution?

Yes. Thank you.

Is there any code have to write to insert permission into database except for..

        public static readonly PermissionRecord ManageHelp = new PermissionRecord { Name = "Admin area. Manage Help Roles", SystemName = "ManageHelp", Category = "Help" };

Thank you.

PermissionRecord manageHelp = new PermissionRecord { Name = "Admin area. Manage Help Roles",
    SystemName = "ManageHelp", Category = "Help" };
var record = _permissionService.GetPermissionRecordBySystemName("ManageHelp");
if (record == null)
    _permissionService.InsertPermissionRecord(manageHelp );

I have many new permissions. What is best practice to add them when application startup ?

Thank you.
