Share in multiple Facebook groups at once

It is possible to share a post in multiple groups at once by using certain applications or social media management tools. These applications can allow you to schedule posts and share them simultaneously across multiple groups on different social networks. However, it is important to check the rules and policies of each social network before sharing content in this way, as some platforms may not allow such practices.

Thank you! Do you know any for individuals that are accepted by Facebook?

No, sorry.
