What can I send to users when they comment on my post?

Private Replies allows Businesses to reply to comments made on their posts with a single message on Instagram. When using this feature, the user will get a message with a reference link to the comment that is being replied. Private replies are allowed within 7 days of the creation date of the comment.
Please note that Private Replies do not open the 24-hour window for standard messaging.
The supported response types are:
- Text only
- Text with Quick Replies
- Image only
- Sticker
