Is Commander’s Strike melee only?

@JeremyECrawford @ChrisPerkinsDnD Is commander's strike melee only or can spell attacks be used as well by the affected player?

Commander's Strike lets you grant a weapon attack to someone. The attack can be melee or ranged. A weapon attack isn't a spell attack. #DnD https://t.co/L5QmVFiF5G

@JeremyECrawford what about a spell that makes a weapon attack such as blooming blade in the SCAG?

Making an attack ≠ casting a spell. #DnD https://t.co/p5rxqKf4k8
