hooks – (Drupal 8) How to alter view and add/change form action in Entity View Attachment (eva) with Table Format

I have 2 related content types (Order & Proposals). In Order Detail page, I attach the Proposals for that order using EVA with table format, like picture below.

enter image description here

I want to add an action button (vote) in EVA output (orange colored box buttons), so that when I click it, it update the Voted-field in the corresponding proposal node. But I don’t know where to start.

The problem is,

I’ve tried using hook_view_pre_render but I can’t find the corresponding object because somehow, Devel-DPM the view object is waaaaayy too large so the debugger gives error message and break my site. I noted the drupal_debug.txt for that particular view has more than 300.000 lines…

here is my alter code

function mymodule_views_pre_render(DrupalviewsViewExecutable $view) {
  if ($view->id() == 'order_proposal_list') {
    $results = $view->result;
    dpm($view); //this breaks my site...
    ddm($view); //this output in drupal_debug.txt with 300.000+++ lines....

Thanks for any helps.
