title: Check if wallet is approved to spend token
body: <p>I was wondering if there's a way to check if a token is already approved for spending. I'm not asking how to approve the token for spending, I've figured that part out via reference: <a href="https://stackoverflow.com/questions/65994914/how-to-approve-a-token-for-spending-on-uniswap-router-contract">How to approve a token for spending on (Uniswap router contract)</a>. I'd like my script to check first before selling a token and then decide, based on the result, to either run approval first or skip it. That way it's not approving a token that's already approved each time it buys and sells the same token. Thanks for all your help anticipation.</p>
