sandbox="" is being added to iFrame embed code automatically

sandbox="" is being added to iFrame embed code automatically, and cannot get rid of it.

Does anyone have a solution for it?

TinyEditor::make('content')
    ->setCustomConfigs([
        'sandbox_iframes' => true,
        'sandbox_iframes_exclusions' => ['IFRAME_DOMAINS'],
    ]),

This should solve the problem. I faced the same issue while embedding videos from api.video. After search, I found that TinyMCE add sandbox layer to prevent XSS attacks. So, it's very important to keep sandboxing works but you can exclude domains you need.

Note I used the full domain of embedding embed.api.video otherwise it didn't work with me
