How to call custom created phtml file in Cms page in magento 2?

Question

I am finding a way to call my custom created phtml file in Cms page. The file is located in Magento_catalog > product > bestseller.phtml, And the way which I am trying is -

{{block class="Magento\Framework\View\Element\Template" name="test_file" template="Magento_catalog::product/bestseller.phtml"}}

{{block class="Magento\Catalog\Block\Product\View\Description" template="Magento_Catalog::product\bestseller.phtml"}}

But the file is not loading in Cms page. Please help me to do it.

Thanks
