The AdminLTE themes support only display of banner text which disappears when you collapse the sidebar. However with a little tweak of the banner code you can use a logo image to display alongside banner text, and on collapse the logo still displays.
Just upload the logo with public access and replace the url in code below and set it as your site banner
</span>
<img src="<link to image>" alt="U" class="brand-image opacity-75 shadow"/>
<span class="brand-text fw-light"><your hub name></span>
Note: This may break the banner on other themes so only implement if other themes are not being used by others.
