The Textarea block is a fundamental component that enables users to input information in forms through a <textarea> element. It provides a larger input area for users to enter and edit multiple lines of text.
To add a Textarea block, create a new form and open the Block Inserter tool. Use the search bar to find the Textarea block and click on its icon to insert it into the editor.
You can also choose the Textarea block from the “Block Inserter” (+) pop-up window when you click on the (+) sign.

Official documentation for these settings controls are available on WordPress.org:
