$resetMemberVar restores a guild-member-scoped variable to its default value defined in the Bot Creator Variables UI. If no default is defined, the stored value is removed. $resetGuildMemberVar is an exact alias.

When called with only a name, it resets the variable for the current command author in the current guild. When a User ID is provided, it resets for that user in the current guild. When both User ID and Guild ID are provided, it resets for the exact guild-member combination.

Use this function to clear warnings, reset XP after a season, remove moderation flags, or restore member defaults after an unban/unmute. After resetting, $getMemberVar returns the default value (if defined) or an empty string. This function does not return any output.
