Irule for inserting header for Google third party cookie deprecation

Hi Guys - Google is starting to deprecate support for third party cookies starting January 2024.   As a temp solution they are asking all impacted customers to insert a http header with a token value.    Can anyone help me with an irule that will insert a header in the http response.     

The requirement is to add the below header in the http response through an irule:

Origin-Trial: TOKEN_GOES_HERE

Thanks for your help.
