My requirement is to add the custom button/menu to add the form elements with in TinyMCE Angular editor.

Here is the template code i have used. My requirement is to add the new button in the toolbar or anywhere within editor.

`<editor
    apiKey="2zr2n................................g26r3pdhfruj"
    formControlName="body"
    [init]="{ 
      plugins: 'advlist autolink link image lists',
      toolbar: 'paste undo redo',
    }"
></editor>`

This is the code i have tried to use in ts file.

`OnInit(editor) {
    editor.ui.registry.addButton('test', {
      text: 'My button',
      icon: false,
      onclick: function () {
        alert('test')
      }
    })   
  }`
