I have a custom HTML Suitelet. Is there a way to get the inactivity "you've been logged out of Netsuite" to pop up when the user is on that suitelet? Currently they would only realize something is wrong when they refresh the page

Return a server widget form and use an inline html field to get your html onto the page

I hear ya. Don't think that will work in my case as my inline html is actually a full fledged react application.

Depends on how you did your react app

yeah you can definitely do that with a react app

Worst case you can do an iframe

I have the app in an iframe. But it doesn't tell me when a user gets logged out

As in an iframe that was added via an inlinehtml field?

Yes
