This is a plugin used by developers for testing purposes, and the fact that the plugin mentioned it is in Beta in its plugin name is very concerning.
As per our website care terms, we do not support plugins, themes, and staging websites as a whole as these websites will be more suited to be maintained by a developer.
Plugin/themes authors usually do not recommend using the beta versions of their plugins/themes on a live, production website.
You can clearly see Elementor's disclaimer here for the plugin.
"This is why we don’t recommend using it on live sites.
We recommend using it on staging environments only, and backing up your entire website before updating."
