I want to replace the button which is standard in odoo. In earlier versions, for example in 14, it was possible to do it in the way that I show below. However, it doesn't work now, and I still don't know how to properly remove the button and replace it with my fields. I will be very grateful for your help.
My edit_weblayout.xml files:
<odoo>
<data>
<template id="Login Layout" inherit_id="web.login_layout">
<xpath expr="//div[@class='text-center small mt-4 pt-3 border-top']" position="replace">
<field />
</xpath>
</template>
</data>
</odoo>
My manifest.py:
"data" : [
"static/src/xml/edit_weblayout.xml",
],
But it doesn't work.
I described all the code that I used above, I will be grateful for the help.

This work in Odoo-16.
Through trial and error, I managed to remove "Powered by odoo" by replacing the block in which it is located.
But I hasten to note that this method also removes the
"Manage database"button, if you suddenly need it, look for another way. But I removed the ability to manage the database inodoo.confand on the UI too, so this way is ok for me.
