Hide/Block the Wazuh app depending by role or config

[frankeros]

Describe the solution you'd like
Certain environments need to exclude the Wazuh app access for certain roles, spaces, or tenants.
The proper approach should be to find a way to deny access through Elastic (ODFE / X-Pack) policies.

Describe alternatives you've considered
An alternative way could be through the Wazuh app (code) with some policies or configs to deny the access.

Additional context
The solution should take care of the indices, patterns, templates, etc, too.

I was investigating a little bit and I found as the Canvas Kibana plugin could be added to features when using X-Pack. This should be tried if it works and adds it to the app.
