Doesn't it rederict to the Facebook application after they click the link?

Normally when I get an URL from Facebook it opens just the Facebook app, but I'm not sure since I'm not using the app anymore since a short time (needs to many priviliges)

no its not redirecting
so is there is any url to access FB app ?
like there is a special link for whatsapp, telegram etc..
which allow us to send data to app & user can select he/she want to send
