Array and string offset access syntax with curly braces is deprecated

Hi,
How are you?
Is there any update to the plugin?

This is an amazing plugin – but on wordpress 5.7 and PHP Version 7.4.15 I get errors such as:

Deprecated: Array and string offset access syntax with curly braces is deprecated in /plugins/wp-testing/src/Facade.php on line 52
