Creating a Menu, How to put "li" inside "a" ?

Good afternoon community!

I made a wordpress theme and have a little doubt.
I created a menu with the following structure:

<nav class="nav-global-cont">
    <ul id="menu-menu-1" class="nav-global">
       <li>
          <a> Item 1 </a>
       </ li>
       <li>
          <a> Item 2 </a>
       </ li>
       <li>
          <a> Item 3 </a>
       </ li>
       <li>
          <a> Item 4 </a>
       </ li>
    </ ul>
</ nav>

For this, I used the following code within my header.php

<? php
    wp_nav_menu (array (
       'menu' => 'Primary Nav'
       'container' => 'nav'
       'menu_class' => 'nav-global',
       'container_class' => 'nav-global-cont'
       'depth' => '2'
    ));
?>

I would like to do otherwise, because the elements “li” contains images of buttons and I desire that all buttons are fully converted into links, not just the text. How do I get the “li” tags to be within the “a”? I wnat to do something like this:

<nav class = "nav-global-cont">
    <ul id = "menu-menu-1" class = "nav-global">
       <a>
          <li> Item 1 </ li>
       </a>
       <a>
          <li> Item 2 </ li>
       </a>
       <a>
          <li> Item 3 </ li>
       </a>
       <a>
          <li> Item 4 </ li>
       </a>
    </ ul>
</ nav>

Thank U!
