How can I have these titles hidden at first, and then display on top of the thumbnails as the user hovers?

Use this code to Website > Website Tools > Custom CSS

.lessons.collection-content-wrapper .grid-meta-wrapper {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%,-50%);
    width: 100%;
    opacity: 0 !important;
}

.lessons.collection-content-wrapper .grid-meta-wrapper * {
    text-align: center !important;
}

li.grid-item:hover .grid-meta-wrapper {
    opacity: 1 !important;
}
