Get sequnece number with refernce to order/post id

i am using mycred to reward customer for order purchase.
And I am using this code to add order id in the log:

add_filter( ‘mycred_log_entry’, ‘mycred_log_entry_func’, 10, 3 );

function mycred_log_entry_func( $content, $entry, $log_entry ) {
if ( $log_entry->ref == ‘reward’ && ! empty( $log_entry->ref_id ) ) {
return $content . ” (#{$log_entry->ref_id})”;
}
return $content;
}
But it is showing post id instead of the order id.
How can I change it to show the relevant order number.
