How much of Aptos is staked?

Excuse me, could you please elaborate on the staking mechanism within the Aptos ecosystem? Specifically, I'm curious to know what percentage of the total Aptos supply is currently staked. Is there a significant portion of the network's tokens locked up in staking, and if so, what are the implications of this for the overall health and stability of the network? Additionally, are there any incentives or benefits for individuals to stake their Aptos tokens, and how do these incentives impact the staking rate?
