Tracking Serverless web Function activation, output and log

I have deployed a Serverless function to test events sent from my PayPal account:

async function main(event) {
    // Default response
    let response = { "body": "Invalid request" };
    console.log('Paypal webhook listener received event: ', event);
    response.body = { event };
    return response;
}
exports.main = main;

This is from the project.yml:

packages:
    - name: webservices
      shared: false
      environment: {}
      parameters: {}
      annotations: {}
      functions:
        - name: paypal-webhook
          binary: false
          main: ""
          runtime: nodejs:18
          web: true
          webSecure: false
          parameters: {}
          environment: {}
          annotations: {}
          limits: {
            timeout: 20000
          }

The function is deployed and sending a request from PayPal webhook simulator is confirmed by PayPal to have been successfully summited. However, I could not find anywhere the output or log of this function, to see what it had received. Looking in the namespace’s Log tab, this function has no activations. This Function is not yet linked to any App, it is standalone. Where can I track its log?
