REST per-client client credential settings not working

Hello,
although this issue seems very simililar to another recent one (REST Authorization from Documentation is not working), it is different indeed.

I’m trying to implement per-client settings (I mean set several client_credentials grant with specific client-id and client-secret); to do so I’m following documentation at https://docs.jmix.io/jmix/rest/getting-started.html#obtaining-access-token.
To begin, I’ve simply copied and pasted the configuration properties

# The client id is my-client
spring.security.oauth2.authorizationserver.client.myclient.registration.client-id=my-client
# The client secret (password) is my-secret
spring.security.oauth2.authorizationserver.client.myclient.registration.client-secret={noop}my-secret
# Enable Client Credential grant for the my-client
spring.security.oauth2.authorizationserver.client.myclient.registration.authorization-grant-types=client_credentials
# Client credentials must be passed in the Authorization header using the HTTP Basic authentication scheme
spring.security.oauth2.authorizationserver.client.myclient.registration.client-authentication_methods=client_secret_basic
# Use opaque tokens instead of JWT
spring.security.oauth2.authorizationserver.client.myclient.token.access-token-format=reference

and similarly

# my-client is the client id we configured previously
jmix.authserver.client.myclient.client-id = my-client
jmix.authserver.client.myclient.resource-roles = rest-minimal

but trying from bash

curl -X POST http://localhost:8080/oauth2/token \
   --basic --user my-client:my-secret \
   -H "Content-Type: application/x-www-form-urlencoded" \
   -d "grant_type=client_credentials"

give me:

{
  "timestamp": "2023-07-05T14:46:35.235+00:00",
  "status": 401,
  "error": "Unauthorized",
  "path": "/oauth/token"
}

and a log in jmix application:

Am I missing something?

thank you

I finally understood the reason why:
I was unintentionally reading and following documentation of 2.0 version,
while my project version in 1.5.2

I suppose that for this version there is not a similar functionality
