Cannot insert HTML content even removing kses filters

I am creating post using the following code, but I cannot make the HTML content go through, they are being stripped automatically..

$post_data = [
  "post_title" => $question,
  "post_content" => $content,
  "post_type" => "bw-faq",
  "post_status" => "publish"
];
kses_remove_filters(); // Disable the kses filters so that HTML  content can pass through
$faq_post_id = wp_insert_post($post_data);
kses_init_filters(); // Enable back the kses filters

I am fighting for long time, but cannot solve it out.. Can someone please help?
