Application task for the line manager

Content (required):

Hello,

I would create a new performance journey with employee tasks and line manager tasks.

I can create a first task (application task -> Performance) for the employee, so he can click on "Go to the application task" and fullfil his performance document.

I would like create a second task for the line manager : I would when he clicks ont the tasks he can go on the Performance of the Employee to review the employee's performance document.

But when I create the task, I don't have any choice on "Application task" field :

How can I create this task ?
