Position fixed is not working with Backdrop-filter

Question

I am tring to make a glass effect in navbar of my website. Here is the code:

HTML:

<nav class="navbar">
    <div class="logo">
        <a href="#">Logo</a>
    </div>
    <div class="mobile_nav">
        <i class="fa-solid fa-bars"></i>
    </div>
    <menu class="menu">
        <a href="#">Home</a>
        <a href="#pricing">Pricing</a>
        <a href="#about">About</a>
        <a href="#contact">Get in Touch</a>
    </menu>
</nav>

CSS:

@import url('https://fonts.googleapis.com/css2?family=Roboto:wght@300;400;500;700;900&display=swap');
:root{
    --black: #0f0f19;
    --gray: #7a7b7f;
    --light-gray: #ddd;
    --primary: #0da87c;
    --white: #fff;
}
*{
    margin: 0;
    padding: 0;
    font-family: 'Roboto', sans-serif;
    box-sizing: border-box;
}
a{
    text-decoration: none;
    color:var(--black);
}

.navbar{
    width:100vw;
    width: calc(100vw - 100px);
    margin-left: 50px;
    border-bottom-left-radius: 20px;
    border-bottom-right-radius: 20px;
    background: #e2e2e2a6;
    display:flex;
    justify-content:space-evenly;
    height:70px;
    line-height: 70px;
    position:fixed;
    top: 0;
    left: 0;
    z-index: 99;
    backdrop-filter: blur(5px);
}
.navbar a{
    padding: 5px 10px;
    color: var(--gray);
    font-size: 14px;
    font-weight: bold;
    transition: all .25s ease-in-out;
}
.navbar menu a:hover{
    color: var(--black);  
}
.mobile_nav{
    display: none;
}
.navbar + *{
    margin-top:70px;
}
@media screen and (max-width: 768px) {
    .mobile_nav{
        display: block;
        position: fixed;
        right: 24px;
    }
    .navbar menu{
        width: calc(100% - 20px);
        margin: 0 10px;
        position: fixed;
        left: 0;
        bottom: -50%;
        display: flex;
        flex-direction: column;
        background-color: #333;
        line-height: 30px;
        border-radius: 30px 30px 0 0;
        padding: 10px;
        transition: bottom .25s ease-in-out;
    }
    .mobile_nav{
        font-size: 24px;
    }
    .active{
        bottom: 0 !important;
    }
}

If you try to view the above code on a mobile screen, you will notice that when you click on the hamburger icon the menu should come from the bottom of the screen but when I add backdrop-filter: unset; to the .navbar class, it is working fine but when I add this, it removes the glass effect.

I'm trying to add the glass effect on both desktop and mobile screens with position: fixed on the inner tag. Help me out please!
