How to implement custom elementor extension plugin?

Question

WordPress

Hello. Tell me please. I've looked all over the internet and haven't found a solution. There is a site on elementor. There is a feedback form module. I need to make my own custom field (input). I implemented this by adding my own test file inside the dynamic-content-for-elementor plugin. But for the custom field to be displayed while adding it to the drop-down list of the form. I need to include my file in 2 places of the plugin.
1. autoload_static.php says: 'DynamicContentForElementor\Extensions\CustomFormFieldTest' => DIR . '/../..' . '/includes/extensions/form/test.php',

2. Extensions.php contains parameters name, category, title, etc.

But the elementor plugin may be updated. I need to create my own plugin. There is a lot of documentation on this. But there is not a single word how I can connect above 2 points. In order not to be dependent on the elementor plugin itself. But at the same time, so that my plugin adds my custom fields to the elementor feedback form. Tell me please. Thank you!
