To create a template, you need to find the "Settings" icon on the top main panel.
When you find it, click on it and see the list.
In this list, you need to find the "Templates" section.
When you've gone to the Templates section, you'll see two types of templates: "Final message templates" and "Feedback templates with the reporter".
To add any template you need to find the inscription "Message text" and below it will be a yellow box.
After you enter the text of the message, you need to click on the green "Add" button.
Done! Your template has appeared in the required template list.
P. S. When you open an already saved template, you can add its translation in several other languages.
