How to Filter Activities by Duration in Hotelbeds API?

I am integrating the Hotelbeds Activities API into my Laravel API, and I need to filter activities by duration. However, I couldn’t find any documentation on how to apply this filter.

Current API Request:
Below is the request I am sending to the Hotelbeds API to fetch available activities for a specific date and destination (Madrid – “MAD”):

{
    "filters": [
        {
            "searchFilterItems": [
                {"type": "destination", "value": "MAD"}  // Destination: Madrid
            ]
        }
    ],
    "from": "2025-02-20",  // Start date
    "to": "2025-02-20",    // End date
    "language": "en",  
    "paxes": [             // Passengers (2 adults, 30 years old each)
        {"age": 30},
        {"age": 30}
    ],
    "pagination": {        // Fetch up to 100 items per page
        "itemsPerPage": 100,
        "page": 1
    },
    "order": "DEFAULT"     // Default sorting
}

API Endpoint:
I am making the request to the following Hotelbeds Activities API endpoint:

https://api.test.hotelbeds.com/activity-api/3.0/activities/availability

Problem:
I want to filter activities based on their duration (e.g., between 3 to 5 hours). However, I couldn’t find any mention of a “duration” filter in the official Hotelbeds API documentation.

Questions:

Does Hotelbeds support filtering activities by duration?
If so, what is the correct filter type and format to use?
Are there alternative ways to achieve this, such as filtering results in Laravel after retrieving them?
Any guidance or working examples would be greatly appreciated!
