data_file example

[HajkWho]

Hi,

could you please provide an example file for the data_file parm?

i got it to work with the text_file option, but in text i can not use the matrix markdown language like
[Concourse Job Link]($ATC_EXTERNAL_URL/teams/((foundation))/pipelines/$BUILD_PIPELINE_NAME/jobs/$BUILD_JOB_NAME/builds/$BUILD_NAME)

I guess i have a problem to understand what a encoded json file looks like 😅
