Storing / Loading states : recall-safe and specific parameters

Hello,
I'm using the custom-module made by Jean-Emmanuel (GitHub - jean-emmanuel/osc-state-example) and it's working perfectly.
But now I would like to make it able to only load certain parameters (define in the onValue script of the load button), and I can't figure out how to do that.
I have already asked ChatGPT, but I always get the same problem : all the state is load.
Here is the onValue script on the save button :

var slot = get('slot_switch');

if (slot) {
    var state = {};
    
    // Liste des paramètres à enregistrer
    var selectedParameters = ['xmin_input', 'xmax_input', 'ymin_input', 'ymax_input', 'number_track']

    // Enregistrez seulement les données sélectionnées dans l'objet state
    Object.assign(state, stateGet(selectedParameters));

    send('custom:module', '/state/save', slot, state);
}

The onValue script of the load button :

// get current slot
var slot = get('slot_switch')
if (slot) {
  var selectedParameter = 'xmin_input';
  send('custom:module', '/state/load', slot, selectedParameter);
}

And the load function of the custom module :

// function for sending a state to all clients
// if provided slot name exists
function loadState(name, selectedParameters) {
    if (name in states) {
        var specificState = {};

        if (selectedParameters && selectedParameters.length > 0) {
            // Si des paramètres spécifiques sont fournis, filtrer le state
            selectedParameters.forEach(param => {
                if (states[name][param] !== undefined) {
                    specificState[param] = states[name][param];
                } else {
                    console.log(`Parameter ${param} not found in state ${name}`);
                }
            });

            console.log(`Sending specific parameters for ${name}:`, specificState);

            // Envoyer uniquement les paramètres spécifiés
            receive('/STATE/SET', specificState);
        } else {
            // Si aucun paramètre spécifique n'est fourni, envoyer l'ensemble du state
            console.log(`Sending entire state for ${name}:`, states[name]);
            receive('/STATE/SET', states[name]);
        }
    } else {
        console.log(`State ${name} not found`);
    }
}

Any suggestions ?
