Find meeting time with room - microsoft-graph-api

Question

I'm facing a problem with https://learn.microsoft.com/en-us/graph/api/user-findmeetingtimes?view=graph-rest-1.0&tabs=http
I'm trying to find an available time slot between my attendees, me and the meeting room.
{
"attendees": [
{
"emailAddress": {
"address": "madreww#mycompany.com"
},
"type": "Required"
}
],
"timeConstraint": {
"timeslots": [
{
"start": {
"dateTime": "2023-01-11T12:00:00.000Z",
"timeZone": "Pacific Standard Time"
},
"end": {
"dateTime": "2023-01-11T15:00:00.000Z",
"timeZone": "Pacific Standard Time"
}
}
]
},
"locationConstraint": {
"isRequired": "true",
"suggestLocation": "false",
"locations": [
{
"locationEmailAddress": "room-accueil#mycompany.com"
}
]
},
"meetingDuration": "PT1H"
}
But the problem if the room "room-accueil#mycompany.com" is booked from 12AM TO 1PM and the response display this available time slot without taking in account the booked room.
Do you have a idea why? And how I can check with this method, if attendees, organizer and the meeting room are all available in a meeting slot time?

}
]
}
But If I use the room in attendees, the room seems to be always booked and always busy
