    I have added a button to tinyMCE, using the same technique as outlined here:

    The button works perfectly BUT only displays the first time tinyMCE is displayed (after loading publii). If I browse to a different post, my custom button disappears.

    Sharing in case anyone can help! Thanks everyone.

    I am using prodocs theme, and publii 0.42.1

    my tinymce.override.json is as follows:

      "toolbar2": "styleselect formatselect sourcecode customInsertButton"

    and my tinymce.script.js is:

    // get an instance of the editor
    var editor = tinymce.editors[0]; //or tinymce.editors[0], or loop, whatever
    editor.ui.registry.addButton('customInsertButton', {
      text: 'My Button',
      onAction: (_) => editor.insertContent(` It's my button! `)

    I was able to get this working with the below (rather hacky) code.

    var editor = tinyMCE.activeEditor; //or tinymce.editors[0], or loop, whatever
    editor.on('init', function(e) {
        console.log('The Editor has initialized.');
        var mybuthtml = ``;
        $( ".tox-toolbar:nth-child(2)" ).css("background", "yellow");
        $( ".tox-toolbar:nth-child(2)" ).append( mybuthtml );
        $("#mycustbut").on('click touchstart', function () {
            console.log("custom but clicked");
            editor.insertContent(` It's my button! `);
