I tried something, and I came up with this (replace it to your css):

.card-body {
    padding: 2em;
}

.feature-list {
    list-style: none;
    padding: 0;
}

.feature-list li {
    display: flex; 
    align-items: center; 
    padding: 0.5em; 
}

.feature-list li::before { /*img styling*/
    content: ''; 
    display: inline-block; 
    background: url('imms.png') no-repeat center center; 
    background-size: contain;
    width: 20px;
    height: 20px;
    margin-right: 0.5em; 
}

This will align your text with the image like this:

Let me know if it works for u; happy coding!
