What does it mean when a Maneki Neko has both hands up?

Excuse me, could you clarify the meaning behind a Maneki Neko figure with both hands raised? I've heard they bring good fortune, but does this particular pose hold any specific significance or symbolism? Is it meant to signify an invitation of wealth and prosperity from all directions, or is there another story or tradition associated with it? I'm quite fascinated by the cultural nuances of these charming figurines and would appreciate your insights.
