how do you change the options for a plugin

how do you change the options for sequence a plugin?
i know how to put one in the sequencer i just can’t remember where the other menu is.

i feel like such a idiot for asking this cause i’m resonably familiar with blender. but still learning of course
and the faq site is down right now so i can’t look there.

it just ive never felt the need to use plugins until now.

thanks.

select it and press N
