Adding 3gp to s9e/text-formatter (Autoimage/Autovideo plugin)

Lej

Hello! I have followed the guide and appended the file type to the configurator file as follows:

namespace s9e\TextFormatter\Plugins\Autovideo;

use s9e\TextFormatter\Plugins\AbstractStaticUrlReplacer\AbstractConfigurator;

class Configurator extends AbstractConfigurator
{
	public    array  $fileExtensions = ['mov', 'mp4', 'ogg', 'webm', '3gp', '3gpp'];
	protected        $attrName       = 'src';
	protected        $tagName        = 'VIDEO';
`
	protected function getTemplate(): string
	{
		return '<video controls="" src="{@' . $this->attrName . '}"/>';
	}
}

I saved changes, and disabled and re-enabled the plugin but 3gp is still just showing as a URL instead of a embedded video. Any ideas? I also tried clearing cache.

EDIT: I am learning that 3gp embedding may not be supported by HTML5
