Hi,

Please follow the screenshots given below.




Note: - For your information, I am using "WP-Editor" plugin to edit files.
You can also download and use it from the link https://wordpress.org/plugins/wp-editor/.

After activating this plugin, you will get the same screen as shown in the screenshot.

Thanks,
Praveen
