refactor your SendHttpRequestAsync method for better readability.

...\src\AdsPush.Vapid\VapidPushNotificationSender.cs

And you can write meaningful steps with descriptive variable names and consistent

private async Task SendHttpRequestAsync(
VapidSubscription subscription,
string payload,
CancellationToken cancellationToken)
{
var request = CreateHttpRequest(subscription, payload);

**AddContentHeaders(request, payload);
AddVapidHeaders(request, subscription);**

return await _client.SendAsync(request, cancellationToken);

}
