camunda 7 how can i use process variable to fill form table

Hello dear camunda users.

i am creating simple bpmn to upload excell file to the process where the file is parsed using external service worker i am using nodejs where after parsing i move to creating new user task.

now from the service worker i assigned variable called “parsed_package_data” to the process variables where i have object of excel data.

how can i use this data to populate the form table for user to see the parsed data in his/her task

i assume i have to fill Data source for the form field but i have no clue what kind of data type it takes i have searched all the documentation but could not find the specific type. maybe you guys can help me out also i have few more questions but for starter this one would be enough.

as you can see in process variables i have package_intake_file wich is created from nodejs script but i also wanted to add gateway to check if it actually got parsed or not.

thank you.
