I have a small javascirpt code and I want it to print in new line

formatPopupBodyText(serverPayload) {
let result = this.formatBusinessHoursText(serverPayload);

    if (serverPayload.PhoneNumbers__c != null && getCurrentCountryCode() === 'IN' && (this.brandName == 'HYN' || this.brandName == 'SUZ')) {
       
        result += `. ${LABEL_NATIONALNETWORK} `;
    }
   
    this.popupBodyText = result;
}

Right now it is showing as below: as a single statement::

We are open from Monday to Friday from 9am to 6pm. Contact us at 80004001. (Call to the national network).

I tried below code but didn’t work:

formatPopupBodyText(serverPayload) {
let result = this.formatBusinessHoursText(serverPayload);

    if (serverPayload.PhoneNumbers__c != null && getCurrentCountryCode() === 'IN' && (this.brandName == 'HYN' || this.brandName == 'SUZ')) {
       
        result += `n ${LABEL_NATIONALNETWORK} `; **//put "n" and tried with "<br/>" as well**
    }
   
    this.popupBodyText = result;
}

Output should be like below means each sentence should be in new line. But right now it is showing in a single statement::

We are open from Monday to Friday from 9am to 6pm.
