defining a smart contract

  signer is defined above no need to define again
  const smartcontract =new Contract(address of smart contract,abi of smartcontract, signer);

calling smart contract function

const onclick = async (a) => {
   
    try {
      const tx = await smartcontract.setCompleted(a.toString());
      const txsign = await tx.wait();
      window.location.reload();
    } catch (e) {
      swal("error in doing transaction you are not admin");
    }
  };

getting data from smart contract functions

 if you want to call data from smart contract follow below
       suppose there is function in smart contract which returns something

 await smartcontract
         .functioninsmartcontract(accounts[0].toString())
         .then((result) => {
           console.log("vesting schedule data ", result);
         });

       suppose there is a call function only or a public variable
       await smartcontract.functioninsmartcontract();
