Can the whole party contribute spells into the Ring of Spell Storing?

@JeremyECrawford Can the whole party contribute spells into the Ring of Spell Storing, or only the one that is attuned to it?

The ring of spell storing allows any creature to cast spells into it. Its second paragraph goes into more depth on that. #DnD https://t.co/OklHkjkExF
