How does staking work on AAVE, and what are the associated risks?

I've heard that staking AAVE tokens can be a good way to earn rewards, but I’m not fully clear on how it works or what the risks might be. Can someone explain the mechanics of staking on AAVE and the potential risks involved? For example, how does the Safety Module function in protecting the protocol, and how does it impact stakers? Any advice on evaluating the potential rewards versus risks would be appreciated.
