How much TIA is staked?

Could you please elaborate on the amount of TIA that has been staked so far? I'm curious to know if there's a significant portion of the total supply that's currently locked up in staking contracts. It would also be helpful to understand the reasons behind staking TIA and how it benefits the network or its holders. Additionally, are there any incentives or rewards associated with staking TIA? Finally, is there a way to track the staking activity and see how it's evolving over time? Thank you for your insights.
