Below is the code for the Header on my LWC page. I am trying to reference the Standard channel_program_members icon. After a lot of tinkering I got it to display however the background color is missing. Conversely if I use the Account Icon only the background is displayed.
<div class="slds-page-header slds-m-bottom_x-small">
<div class="slds-page-header__row">
<div class="slds-page-header__col-title">
<div class="slds-media">
<div class="slds-media__figure">
<span class="slds-icon_container slds-icon-standard-channel_program_members" title="screening">
<svg xmlns="http://www.w3.org/2000/svg" class="slds-icon" aria-hidden="true">
<use xlink:href="/_slds/icons/standard-sprite/svg/symbols.svg#channel_program_members"></use>
</svg>
<span class="slds-assistive-text">screening</span>
</span>
</div>
<div class="slds-media__body">
<div class="slds-page-header__name">
<div class="slds-page-header__name-title">
<h1>
<span>Candidate Scrrening</span>
<span class="slds-page-header__title slds-truncate" title="test">{HeaderTitle}</span>
</h1>
