<script>
        let element = document.evaluate(
            "/html/body/div[2]/div[2]/div[2]/div/div/div[2]/div/div/div",
            document,
            null,
            XPathResult.FIRST_ORDERED_NODE_TYPE,
            null
        ).singleNodeValue;

        if (element) {
            element.style.height = "100vh";
        } else {
            console.error("Element not found!");
        }

</script>

when i inspected the rendered map there was one with id map-container and inside there were two divs the inner one had height 0 causing the problem so i selected the x-path of the inner div and used javascript to modify the height to 100vh

Here is the picture
