How do I stop prompts and pop-ups in MacBook Pro Catalina?

I edit films, mostly with FCPX. Every time I export out a film or sequence I get pop-ups telling me I've just 'shared' something. Sometimes I have to export twenty sequences in a row ... and I get twenty pop-up boxes appearing on my screen. How can I turn off this function in Catalina or FCPX?

All ears,

Ben
