Hi @mojtabaebrahimi13
at the moment Antispam Bee does only protect the comment form and no other form (eg registration) or form plugin.
But you can use the Honeypot field in Elementor forms to protect them.
There are more settings, snippets and plugins that support Elementor forms. Maybe there will be more support in v3 of Antispam Bee.
All the best,
Torsten
