I assign a claim to a user in a certain endpoint

await userManager.AddClaimAsync(user, new Claim("role", "admin"));

and retrieve it from within another endpoint via the injected HttpContext.

app.MapGet("", (HttpContext context) =>
{
    var cp = context.User;
    var response = string.Join(", ", cp.Claims.Select(c => $"({c.Type},{c.Value})"));
    return TypedResults.Ok(response);
});

The output is not (role, admin) but (http://schemas.microsoft.com/ws/2008/06/identity/claims/role,admin).

The framework under the hood automatically associates my "role" with ClaimTypes.Role? Is there any trick to stop this behavior?
