How to enable intellisense in VSCode for chaincode development (Hyperledger Fabric)

Question

Facing issues with vscode intellisense not working while writing chaincode. This is Hyperledger Fabric chaincode development with vscode

'use strict';

const { Contract } = require('fabric-contract-api');

class CertnetContract extends Contract {

constructor() {
    super("certnet"); 
}

async instantiate(ctx) {
    console.log("chaincode was successfully deployed");
}

//Create Student Asset
async createStudent(ctx, studentId, studentName, studentEmail) {

    //create compositeKey
    const studentKey = ctx. -----> here the intellisense not working
}

}
