Additional context

[ctran88]

had to go with a dynamically typed constructor instead of using the more strongly typed setters because the PHP codegen has the channel prop typed as MagicLinkChannel, which looks like

passage-php/generated/lib/Model/MagicLinkChannel.php

Lines 41 to 48 in 5384ee9

	class MagicLinkChannel
	{
	/**
	* Possible values of this enum
	*/
	public const EMAIL = 'email';
	public const PHONE = 'phone';

so MagicLinkChannel::EMAIL is actually a string, which throws a type error since CreateMagicLinkRequest->setChannel is expecting the class.

Haven't QAed just yet, but code looks good to me.
