Missing Host Prototype in a discovered host

[TheBonaZabbix]

Hi all!
It is possible to create:
A template with discovery rule and host prototype
In the host prototype I linked a template which, in turn, contains a detection rule with another host prototype.

I'm trying but it's not working.
The first template works fine and the hosts are detected.
Detected hosts have the linked template configured in the host prototype.
But if I look in the Detection Rule there is no host prototype.
This is the first Template


This is the Template applied to the Host Prototype


In the discovered host missing the Host Prototype



Many thanks !

I think I've found the answer-->
From documentation: Zabbix does not support nested host prototypes, i.e. host prototypes are not supported on hosts that are discovered by low-level discovery rule.
