How to send a response from the custom module?

I built a custom web-push module and I want to return a message from that module.

Below is the code

This is my module

const webpush = require("web-push");

exports.pushNotification = function (options) {

    options = this.parse(options);

    const mailto = options.mailto;

    const publicKey = options.publickey;

    const privateKey = options.privateKey;

    const endpoint = options.endpoint;

    const authKey = options.authKey;

    const p256dh = options.p256dh;

    const pushConfig = {

        endpoint: endpoint,

        keys: {

            auth: authKey,

            p256dh: p256dh,

        },

    };

    webpush.setVapidDetails(`mailto:${mailto}`, publicKey, privateKey);

    webpush

        .sendNotification(

            pushConfig,

            JSON.stringify({

                title: "New Comment",

                content: "New Comment added!",

                openUrl: "/help",

            })

        )

        .catch(function (err) {

            console.log(err);

        });

    return {

        message: "Push notification sent"

    }

}

This is the hjson

   action:"pushNotification",

   groupTitle:"Custom Actions",

   groupIcon:"fas fa-lg fa-database comp-data",

            {

               name:"message",

               type:"text"

            }

         ]

      }

   ],

   properties:[

      {

         group:"Web Push Properties",

         variables:[

            {

               name:"mail",

               optionName:"mail",

               title:"mail",

               type:"text",

               required:true,

               defaultValue:"",

               serverDataBindings:true

            },

            {

               name:"publicKey",

               optionName:"publicKey",

               title:"Public Key",

               type:"text",

               serverDataBindings:true,

               type:"text",

               defaultValue:""

            },

            {

               name:"privateKey",

               optionName:"privateKey",

               title:"Private Key",

               type:"text",

               defaultValue:"",

               serverDataBindings:true

            },

            {

               name:"endpoint",

               optionName:"endpoint",

               title:"End Point",

               type:"text",

               defaultValue:"",

               serverDataBindings:true

            },

            {

               name:"authKey",

               optionName:"authKey",

               title:"Auth Key",

               type:"text",

               defaultValue:"",

               serverDataBindings:true

            },

            {

               name:"p256dh",

               optionName:"p256dh",
               title:"p256dh",
               type:"text",
               defaultValue:"",
               serverDataBindings:true
            }
         ]
      }
   ]
}

This is the server connect

This is the response where I can’t see my module response
