How to check WSTETH earnings?

Hello, how do we check ithe earnings we get from wstETH? How do we know it is accruing or not?

I am fairly new with DEFI and ETH Staking.

As background to my question, I had converted around 1500$ ETH to wstETH and deposited to AAVE V3. I leveraged this thru deposit-borrowing and now is currently 3000$ worth of wstETH.. Since wstETH or stETH is accruing interest at around 3.5% per annum, I should be getting around 105$ per year (assuming its 3000 x 3.5%).

My question is that how do we know if the ETH value or number is increading or not with wstETH? As my experience with stETH was that I could check the value per day if it is increasing. But with wstETH, how do we check it or track?
