How to modify the uploads directory for wp.media.frame assigning an subfolder name

Question

To be better organized I must be able to manage the media independently of the user.

So in addition to restrict user to see only these files(images, docs, videos), I need to insert media for each organization inside a new uploads subfolder.ex: uploads/user-subfolder I don't want to use "author" as a basis for comparison because I must create posts for user before it exist and it is easier to define a media subfolder by user to be sure to restrict access media to each one and that can be later associated.

This subfolder is well created and works, but I can't find any explanation in documentation how to modify the directory of media uploaded with wp.media.frame

Inside custom post the User or me define a subfolder name. Then, this one must be used for the new directory to upload media.

So, opening a custom wp.media.frame this must be linked to an uploads subdirectory. It will be different for each organization.

I don't think that apply_filters( 'upload_dir', array $uploads ) can be used in my case because this filter will be apply for all without distinction.

Currently I use this jQuery script to open/close wp.media.frame .

/**
 * Define media_lib_frame as wp.media object
 */
const media_lib_frame = wp.media({
    title: 'Ajouter une image',
    multiple: false,
    library: {
        type: 'image',
        uploadedTo : wp.media.view.settings.post.id 
        // is this the parameter that defines the folder path ? 
    }
});

/**
 * On close, get selections and save to the hidden input
 * plus other AJAX stuff to refresh the image preview
 */
media_lib_frame.on('close', _ => {
    const selection = media_lib_frame.state().get('selection');
    const gallery_ids = selection.map(attachment => attachment['id']);
    const ids = gallery_ids.join(",");
    $('input#idImage').val(ids);
    loadImage(ids);
    if($('#idImage').val() == ''){
        $('#image_preview').remove('');
        $('#btnOpenMediaLibFrame').prepend('<span>Ajouter une image</span>');
    }
    if($('#image_preview').length){}else{
        $('#idImage').before('<img id="image_preview">');
    }
});

/**
 * On open, get the id from the hidden input
 * and select the appropriate images in the media manager
 */
media_lib_frame.on('open', _ => {
    $('#btnOpenMediaLibFrame span').remove();
    if($('#image_preview').length){}
    else{$('#btnOpenMediaLibFrame').append('<img id="image_preview">');}
    const selection = media_lib_frame.state().get('selection');
    const ids = jQuery('input#idImage').val().split(',');
    ids.forEach(id => {
        const attachment = wp.media.attachment(id);
        attachment.fetch();
        selection.add(attachment ? [attachment] : []);
    });
});
//$('#btnImage')
    $('#btnOpenMediaLibFrame').click(e => {
    e.preventDefault();
    media_lib_frame.open();
});
