enabling image upload

I am trying to enable the image upload on comments. I will set the comments user only so there is no security issue.

I tried this but didn't work. what settings I need to enable for allowing image block, gallery block and uploading.
Is there a list I can see all available settings ?

```php

add_filter( 'blocks_everywhere_editor_settings', function( $settings ) {
$settings['iso']['blocks']['allowBlocks'][] = 'blocks-everywhere/support-content';
$settings['iso']['blocks']['allowBlocks'][] = ['**/imagecard'];

return $settings;
} );

add_filter( 'blocks_everywhere_admin', '__return_true' );
add_filter( 'blocks_everywhere_admin_cap', '__return_empty_string' );
```


Start by reviewing the blocks_everywhere_editor_settings filter and its allowBlocks entries, then determine how comment users, image and gallery blocks, and uploads are configured. Done means identifying the required settings and documenting or implementing a supported configuration, with the available settings listed clearly.
