Creating a login/signup modal on everypage "Reusable components/Symboles"

Hello,

I’m still looking around to see what is easily doable in Wappler.
One thing I’m not sure about is the use of “Reusable components/Symboles” for exemple a Login/Sign Up modal on everypage of the website.

So the modal itself is pretty simple to do.
But how do you copy it to all the pages easily and easily maintain it.

I have seen that in PHP you have the includes files and in node.js the template are coming.

But what I have understood you can only put in those the html/css elements not the app connect and server connect actions.

So the design of the modal can be duplicated easily but not its logic.

Am I missing something ?

Thanks a lot,
