Yes, you should have a file called cart-drawer.liquid most of the time it is a snippet. You would go in here and in between </form> and </cart-drawer-items> you would add your code to display products.

</form>
//** YOUR CODE HERE **//
</cart-drawer-items>

Do you have a preview link to your store, I would need to inspect it since it isn't the Dawn Theme

I would place your code here. After the closing <div data-products></div> but before the closing </div> for <div class="drawer__scrollable">
