How to set variable on Redwood page performance-document to get the evaluationId

I am trying to add a card in the Redwood performance-document page that will redirect the user (with the role of a manager) from the Performance document of a direct employee to the page performance-select-and-track-participants for the respective employee. I have set the navigation flow on the Action Chain linked to the card, however the performance-select-and-track-participants requires some parameters for this flow to work. One of the parameters is evaluationId, which is linked to the employee, so I cannot hardcode it (obviously). I wanted to link this parameter to a variable on the page, however the page is very poor
