inconvenience with style_formats TinyMCE 6.2.0

Question

I am wanting to use style_formats and I am not being able to succeed in adding it in toolbar1

tinymce.init({
    selector: 'textarea',
    //editor_deselector: 'EditorManager',

})

commenting everything and leaving the selector and style_formats works normally, but I am not being able to add it to toolbar1

resolved. The call to 'styles' was added in the toolbar and the 'importcss' plugins were commented
