Is there a way to open the Email Author Layout with pre defined email template in Lightning Experience. I know that earlier we don't have the possibility to do this since LEX was not supporting the URL hacks. But as per spring 20, LEX is supporting the URL Hacks.
Classic : /_ui/core/email/author/EmailAuthor?rtype=003&p3_lkid={!Opportunity.Id}&retURL=/{!Opportunity.Id}&[email protected]&template_id=00X40000001XQwz
What is the equivalent url for Lighting Experience ??
