Button to reload jinja macros in Developer Tools > YAML

Whilst I can reload the templating macro using the service call:

homeassistant.reload_custom_templates

It would be nice if this could be added to the list reloadable items in Developer Tools > YAML.

When I try to activate this service (homeassistant.reload_custom_templates from x.x.x.x:8123/developer-tools/service) I get the error message: “Unable to find service homeassistant.reload_custom_templates”.
The service is not listed in the available items containing “reload”.
All other parts of homassistant seem to work with no problem. ( Home Assistant 2023.1.7 Frontend 20230110.0 - latest, running on Debian Linux)
Any hints where to search for the missing service or how to install it?

You can make your own button for lovelace. But yes agree voted.
