Get ID of recently created User Role using Identity .net core 2.0

Question

Hi, I have created new role using identity and want to get Id for this recently created Role on result.succeded.

I'm using the approach like below

public async Task<IActionResult> CreateRole(CreateRoleViewModel model)
{
if (ModelState.IsValid)
{
IdentityRole identityRole = new IdentityRole
{
Name = model.RoleName
};

IdentityResult result = await roleManager.CreateAsync(identityRole);

if (result.Succeeded)
{
  // Here I want to get the RoleId created newly.
return RedirectToAction("Index", "Admin");
}
foreach(IdentityError error in result.Errors)
{
ModelState.AddModelError("", error.Description);
}
}

return View();
}

 Thanks in advance :)
