You can grant other user roles access to the feed settings by using a plugin such as User Role Editor and giving a role the manage_instagram_feed_options capability, or by adding the following snippet to your functions.php file:
/* Upgrade the Editor Role */
function sb_custom_capability( $cap ) {
return 'edit_posts'; }
add_filter( 'manage_instagram_feed_options', 'sb_custom_capability', 10, 1 ); 
If you need to share access to the plugin settings, add the following snippet to your functions.php file:
/* Upgrade the Editor Role */
function sb_custom_capability( $cap ) {
return 'edit_posts'; }
add_filter( 'sbi_settings_pages_capability', 'sb_custom_capability', 10, 1 );
