Lost Message Blocks

Hello!

I have recently performed an update on the theme and it seems I have lost functionality on the message blocks(https://demo.graphene-theme.com/features-and-functionalities/message-blocks/)

I looked in my theme folder and it seems I am missing some important files, based on looking at this:
https://docs.graphene-theme.com/Message_blocks_shortcodes

For example, I don’t see /includes/theme-shortcodes.php and I don’t see require( get_template_directory() . ‘/includes/theme-shortcodes.php’ ); in functions.php.

Should I reinstall the theme or perform the steps in the above in order to fix the issue?

I looked in a newly DLed version of the theme (1.9.4) and I don’t see /includes/theme-shortcodes.php in it. Has this been removed?

They are also missing from the editor so I can’t use them in Visual mode.

Thanks!
