To embed a link in Messenger, follow these steps:
1. Open the Messenger app on your device and log in to your account.
2. Start a conversation or open an existing one with the person or group you want to send the link to.
3. In the text input box where you type your message, tap or click on the "+" or "Attach" icon. It is usually located near the text input field.
4. Select the option labeled "Share Link" or "Add a Link." The exact wording may vary depending on the Messenger app version you're using.
5. A new window will appear, allowing you to enter the link you want to embed. Type or paste the URL into the provided text field.
6. Messenger will automatically fetch the metadata for the link, including a preview image, headline, and description. You can also customize the preview by tapping or clicking on it and selecting a different image or removing the preview.
7. Once you are satisfied with the preview, tap or click the "Send" button to share the link in your conversation.
Remember that some Messenger apps or platforms might have slightly different interfaces or options, but the basic steps should remain similar across different versions.
