Result of API execute-command?

I am trying to manually run a check on agents and read the output.
I was able to execute the command on the agent but how can I see the return value and output?

[root@icinga2 ~]# curl -k -s -S -i -u root:icinga -H 'Accept: application/json' -X POST 'https://localhost:5665/v1/actions/execute-command?pretty=1' -d '{"host":"test02","ttl":15,"endpoint":"test02","command_type":"CheckCommand","command":"icinga"}'
HTTP/1.1 202 Accepted
Server: Icinga/r2.13.7-1
Content-Type: application/json
Content-Length: 208

    "results": [
            "checkable": "test02",
            "code": 202,
            "execution": "c2cc992d-5c15-4b9e-b5cd-ff315998cfe8",
            "status": "Accepted"

The documentation sais, that the execution can be queried, so I did this:

[root@icinga2 ~]# curl -k -s -S -i -u root:icinga 'https://localhost:5665/v1/objects/hosts/test02?pretty=1' | grep -A 5 executions
                "executions": {
                    "c2cc992d-5c15-4b9e-b5cd-ff315998cfe8": {
                        "deadline": 1678883958.22948,
                        "pending": true

And after some time it just looks like this:

[root@icinga2 ~]# curl -k -s -S -i -u root:icinga 'https://localhost:5665/v1/objects/hosts/mv-test02?pretty=1' | grep executions
                "executions": {},

So, how can I get the output of the check-command?

I never tried to get the result of the check-command directly but I get them from the service.

        url = "https://" + self.fqdn + ":5665/v1/objects/services"
        data = {
            'filter': 'match("{}*",'.format(self.service_prefix),
            'attrs': [

I can see the “last_check_result”.
But this is the result of the regular check that is also visible in icingaweb2.

The result of my execute-command is not visible in icingaweb2.
Should it be visible there?

Maybe not but I had an idea: could it be, that you need to request the result like I needed with the last_check_result in attrs while querying the service object.

The output of
curl -k -s -S -i -u root:icinga 'https://localhost:5665/v1/objects/hosts/test02?pretty=1'
contains a last_check_result section.
But it has the values of the configured icmp check.
