Facebook provides a new feature for Messenger services. Later users can easily quote or reply to messages that are more personal and specific.
Summarized from Ubergizmo on Thursday (3/21/2019), the Facebook feature on Facebook is similar to those already present on WhatsApp.
In Messenger, the way the new features work is not much different from WhatsApp, that is, the user simply does a push gesture - hold the message you want to reply to, then the option will appear to reply.
And when the message is sent it will also include a sign of a particular message that you want to reply to, so that the user who receives the message knows what is being discussed.
For the record, this feature only works on the mobile version and there is no version on the desktop. Allegedly, soon Facebook will also present these features on the desktop.
