How to use the @jupyterlab/rendermime.standardRendererFactories.filter function in @jupyterlab/rendermime

function getRenderers(options) {
  if (!_renderers) {
    _renderers = standardRendererFactories.filter(f => {
      // filter out latex renderer if mathjax is unavailable
      if (f.mimeTypes.indexOf("text/latex") >= 0) {
        if (options.mathjaxUrl) {
          return true;
        } else {
          console.log("MathJax unavailable");
          return false;
        }
      } else {
        return true;
      }
    });
  }
  return _renderers;
}
// rendering cells

getRenderers() {
        if(!this._renderers) {
            this._renderers = standardRendererFactories.filter(factory =>
                factory.mimeTypes.includes('text/latex') ?
                    (typeof window !== 'undefined' && window.MathJax) : true);
        }
        return this._renderers;
    }
