Hi. I''m working on a Odoo v16. What I want to do is basically display some custom xml in the backend of the community version. With the code bellow, it worked fine in a 14.0. But on a 16.0 my stuff is displayed above the top Navbar (The one where the clickable menus are displayed). And this Navbar is at the bottom of the screen with the code bellow
Should I still inherit webclient_bootstrap? Or has this changed in 16.0?

<template id="custom_template" inherit_id="web.webclient_bootstrap" name="Custom Template">
    <xpath expr="//t[@t-set='body_classname']" position="after">
        My stuff
   </xpath>

</template>
