How to Delete Facebook Messages via Facebook API?

Is there a way to retrieve all Facebook Message ids with the read mailbox permission and then delete them all one by one? Everyone is crying about how it's difficult to delete your chat/message history. I wondered if there was an easy way to write an app to do this.

Normally you would issue an HTTP DELETE call to https://graph.facebook.com/messageID?access_token=... But it appears that this is an API call that either require special whitelisting from Facebook or isn't currently supported because it does not work right now and returns "Unsupported delete request."

Open the facebook using https://mbasic.facebook.com/messages/?_rdr

Enable jQuery using jQueryify extension you installed. Then go to your chrome developer tools> sources > snippet and create a new snippet and paste the following code and run it.

// Code snippet for facebook messages removing:

var WHITELISTED_USERS_X = [];
function removeElement(elementId) {
    // Removes an element from the document
    var element = document.getElementById(elementId);
    if (element) {
        element.parentNode.removeChild(element);
    }
}

function addElement(parentId, elementTag, elementId, html) {
    // Adds an element to the document
    //     removeElement
    removeElement(elementId);
    var p = document.getElementById(parentId);
    var newElement = document.createElement(elementTag);
    newElement.setAttribute('id', elementId);
    newElement.innerHTML = html;
    if (p) {
        p.appendChild(newElement);
    } else {
        var body = document.getElementsByTagName("body")[0]
        body.appendChild(newElement);
    }

}
addElement("body", "div", "123x", "hello World23");
console.log(`getOlderMessagesLink()`);
console.log(getOlderMessagesLink());
var aLinks = document.querySelectorAll('h3 a'), i;

for (i = 0; i < aLinks.length; ++i) {
    let currentLink = aLinks[i];
    currentLink.style.color = currentLink.style.color == "black" ? "red" : "green";

    $.get( currentLink.href, function( data ) {

    getPayload1(currentLink.href).then(payLoad=>{
    let abLink = currentLink.href;
    let deleteApiLink = abLink.split('?').pop().split('&');
    deleteApiLink.splice(1 , 0, `tids=${deleteApiLink[0].split('=').pop()}`)
    deleteApiLink = deleteApiLink.join("&").split("#").shift();    
    const apiLink = `https://mbasic.facebook.com/messages/action_redirect?` + deleteApiLink;

    $.post(apiLink, payLoad ).done(function( data ) {
    let mydeletehref = findInParsed(data, "a:contains('Delete')");
    const username = currentLink.innerText;
