Is there a way to update a job's original payload?

[DevanshB10]

I am using agenda job, to trigger a request with some payload as follows:

exports.addJob = catchAsync(async(req, res, next) => {
    var requestBody = req.body;
    var user = requestBody.user;
    var scheduledTime = new Date(requestBody.scheduledTime).toUTCString();
    var content = requestBody.content;
    var hash = getEncryptedHash(user, scheduledTime);
    agenda.define(hash, async (job) => {
        try {
            var postData = {
                content: content,
                currentUser: user
            }
            var postUrl = `${process.env.DOMAIN}/api/v1/min-mum` + '/create-post';
            var payload = {
                url: postUrl,
                method: 'POST',
                data: postData,
                headers: {
                    'Content-Type': 'application/json',
                }
            };

            await axios(payload);
            
        } catch(err) {
            console.log(err);
        }
    });
    await startAgenda(hash, scheduledTime);
})

As you can see, I am saving the content and the scheduled time as submitted by the user,
Now the user can update the schedule as well, how do I update the existing job in this case? Is there a way to do this, or do I need to cancel this job and add another job?
