How do i add shadow effect onto a section divider?

[sashavalentina]

I'm using clip-path to create this section divider. I wanted to add a shadow effect on the 6 sides of this section. I tried box shadow but it couldn't show the shadow on the sides of the section divider. The image below is the shadow effect that i wanted to create on my section divider.

<section style=" clip-path: polygon(0 0, 50% 100px, 100% 0, 100% 100%, 0 100%);box-shadow: inset 0 0 10px 0 black;margin-top: -10px;padding-bottom: 3rem;background-color: #ffffff;">
    <div class="container">
        <div class="row">
        </div>
    </div>
</section>

Can someone show a helping hand here, cuz i have been figuring this out since forever. It will be a great help!
