You can simply install a plugin called “SVG Support” and configure the options to your needs or if you want to reduce the amount of plugins on the site you can add some code to the theme’s (child theme if it is a market place theme) function.php file to enable SVG support
[js]
function add_file_types_to_uploads($file_types){
$new_filetypes = array();
$new_filetypes[‘svg’] = ‘image/svg+xml’;
$file_types = array_merge($file_types, $new_filetypes ); return
$file_types;
}
add_action(‘upload_mimes’, ‘add_file_types_to_uploads’);
[/js]
Here is an article that does a great job explaining it. https://themeisle.com/blog/add-svg-to-wordpress/
