Bot Flowbuilder - Simple functions

Feature Request Summary: 

Add the ability to use simple functions like to get the current time, format text, initialize variables and so on.

Description/Use Cases: 

Allows for more usability/variety and does not require third party tools to be used instead.

Business impact of limitation or missing feature:

For an API call after the customer provided some data I needed the current time and time before 365 days. To complish this I needed to create a Microsoft Power Automate flow which could be queried with an API to get the current time there since there is possibility to get the current time in the format I needed from Zendesk since also responses can not be formatted.
