Proper way to do_action inside of shortcode code

Hey ya’ll,

Trying to figure out the best way to add an action hook to my plugin.

Currently, my shortcode function does it’s thing and then returns the output.

I want to add an action hook at the very end before the output is returned so users can add some custom features/functions that wouldn’t be possible via shortcode attributes.

Because the output is being returned, I can echo the do_action call. So, what is the best way to provide this hook and have the output of the hook be returned with the shortcode output?

Many thanks!
