How do I open my Facebook page in the Facebook app by starting the activity

I am facing a problem opening my Facebook page through the Facebook application, and the activity started. The process actually succeeded and I opened the Facebook application, but it did not open my page, but opened it and put it in normal mode.

@Jihed if you directly paste a link in the firebase database then when the data is called everything after the slash(/) is not called that means it is not read by the firebase so do one thing I have given an edited version of your link replace this whole link the try to get the link in a label and if it’s perfectly coming the directly use activity starter
