Wordpress Woocommerce how to get the data array of the product that is selected in the variation?

Question

WordPress

Guys, point me in the right direction. The essence of the question is that there is a variable product, in the variations of which there are simple products. I need to get an array of data (ID, fields, etc.) of the product that is selected in the variation. Are there standard WC functions for getting data, or will there be workarounds?
