How to use the pdfplumber.utils.objects_overlap function in pdfplumber

by_center = utils.cluster_objects(words, lambda x: (x["x0"] + x["x1"])/2, 1)
    clusters = by_x0 + by_x1 + by_center
    
    # Find the points that align with the most words
    sorted_clusters = sorted(clusters, key=lambda x: -len(x))
    large_clusters = filter(lambda x: len(x) >= word_threshold, sorted_clusters)
    
    # For each of those points, find the rectangles fitting all matching words
    rects = list(map(utils.objects_to_rect, large_clusters))
    
    # Iterate through those rectangles, condensing overlapping rectangles
    condensed_rects = []
    for rect in rects:
        overlap = False
        for c in condensed_rects:
            if utils.objects_overlap(rect, c):
                overlap = True
                break
        if overlap == False:
            condensed_rects.append(rect)
            
    if len(condensed_rects) == 0:
        return []
    sorted_rects = list(sorted(condensed_rects, key=itemgetter("x0")))

    # Find the far-right boundary of the rightmost rectangle
    last_rect = sorted_rects[-1]
    while True:
        words_inside = utils.intersects_bbox(
            [ w for w in words if w["x0"] >= last_rect["x0"] ],
            (last_rect["x0"], last_rect["top"], last_rect["x1"], last_rect["bottom"]), 
        )
