Another option is to implement and register your own SecurityTokenValidator. To do so you need to create a class implemented ISecurityTokenValidator interface:

//using Microsoft.IdentityModel.Tokens

public class CustomValidator : ISecurityTokenValidator
{
   //interface implementation
   ...
}

and register it as an additional token validator via JwtBearerOptions.SecurityTokenValidators property:

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
    .AddJwtBearer( options => {

        options.SecurityTokenValidators.Add(new CustomValidator()) 
    });
