How to link_to collapse on another page using anchor

Link on notifications page:
<%= link_to main_app.recipe_path(notification.second_target.recipe, notification.second_target.id, anchor: "comment_#{notification.target.id}"), class: "dark-link" do %>

On the recipes page, I displayed all reviews comment
<section class="comment-container">
    <p class="notifications-p">
      <button class="btn btn-default btn-sm mb-2" type="button" data-toggle="collapse" data-target="#collapseComments-<%= review.id %>" aria-expanded="false" aria-controls="collapseComments-<%= review.id %>">
        <% unless review.comments.blank? %>
          <small><i class="fa fa-comments text-muted"></i>View comments<i class="fa fa-chevron-down text-muted"></i></small>
        <% else %>
          <small><i class="fa fa-comment text-muted"></i>Add Comment<i class="fa fa-chevron-down text-muted"></i></small>
        <% end %>
      </button>
    </p>
    <div class="collapse" id="collapseComments-<%= review.id %>">
      <div class="comments-card">
        <%= render "comments/widget", commentable: review %>
      </div>
    </div>
</section>

<li id="comment_<%= comment.id %>" class="comment">

</li>
