Adding photos to the campaign in the tinymce editor

Hey!
I would like to understand how to enable the function of uploading photos to a post via tinymce editor or some other plugin. I wanted to do this by editing the file located in:

/wp-fundraising-donation/views/public/fundraising/dynamic-page/dashboard/add-campaign/campaign-intro.php

	<?php
		$post_content = isset( $post_data->post_content ) ? $post_data->post_content : '';
		$editor_id    = 'campaign_details_editor';
		$settings     = array(
			'media_buttons' => false,
			'textarea_name' => 'campaign_post[post_content]',
			'drag_drop_upload' => true,
		);
		wp_editor( $post_content, $editor_id, $settings );
		?>

I found there the code responsible for disabling the button to hide adding media, I changed it to “true” and the button showed up, however, it shows all photos in the wordpress gallery, including other users, and I can’t add a photo. I want it to be easy to add photos to a fundraiser.

Alternatively, it can be replaced with gutenberg, in which case please give instructions on how to do it ??

I would appreciate any help or code to help me do this.
