Import facebook messenger id (subscribers)

Hello everyone, my name is Mário Guimarães, I’m new to the community
And before asking that question I tried to find the answer by doing a search
Two things may have happened and that’s why I didn’t find the answer
First: I don’t know how to search (I really believe in this possibility)
Second: this is really very basic and I don’t know how to do it, so this question doesn’t need to be on the forum. And I apologize in advance if that is the case. But I still don’t know how to do it

The point is that I don’t know if it is possible or how to import the list of subscribers that I have on a Facebook page

To be honest, I don’t even know if this is necessary or if when connecting the bot they will already be listed as subscribed.

This is not what happened with other tools I tested, so I ask if there is a way to do this.

I have a list with just over 378 thousand subscribers that I used another tool to automate the bot.

I would like to use botpress.

Can someone show me a way?
