clientid should be checked in the if condition too

clientid should be checked in the if condition too

I know that but I realized that clientid flag shouldn't be used if it is public share. I tried to use clientid flag by leaving it blank but it didn't work like that, I think clientid flag shouldn't use at all for public share. So, that's why I excluded clientid flag. @Kishan-Dhakan
