Liquidity assets earnings: how to check them?

Hi! I just added to the liquidity pool BUSD / USDT some BUSD, now I can see them in my account’s liquidity assets tab. How can I see how much I earned so far with the trading fees?
With the mining is pretty straightforward since there are rewards accumulating after staking, but here?
Please let me know if you need further explanation if something is not clear.
Thanks in advance!
