How i can add Users from usergroup to custom field if component is selected

[Alibek]

I want add Users from usergroup to custom field if component is selected
let's say I have 3 components "A", "B", "C".

If component "A" is selected when creating a task, then users in "group1" are added to the custom field, and there are also groups with users.

This is all that I plan to do through the script launching script I plan to install at the stage of creating tasks and also add a lisner that will also check the same script.

Thanks in advance)
