I am trying to configure the feature to add watermark to my render requests, does it support the following formats?

For Text Watermark:
opacity - Is this supported?
offset - Is this supported?
alignment.vertical and alignment.horizontal - Are these supported?

For Image Watermark:
opacity - Is this supported?
offset - Is this supported?
width - Is this supported?

// 4. Add watermark (text or image) if specified - LAST
    const watermarkType = renderSettings?.watermark_type || 'text';
    
    if (watermarkType === 'text' && renderSettings?.watermark_text) {
      // Text watermark with dynamic font size based on scale
      const fontSize = 15 + ((renderSettings.logo_scale || 0.15) * 100);
      
      const watermarkTrack = {
        clips: [
          {
            asset: {
              type: "text",
