Is mana used in Metaverse?

Could you possibly elaborate on whether or not Mana serves a purpose within the Metaverse? I'm quite curious to understand its role, if any, in this virtual realm. Could you explain how it's used, and perhaps provide some context as to why it's significant? Additionally, is Mana a necessary component for participating in the Metaverse, or is it merely an optional feature? I'm interested in gaining a deeper understanding of this concept and how it fits into the broader picture of the Metaverse.
