[VDGS Not Working at EGLL with Premium]

Good observation, it’s MSFS24 and I’m a newbie to it, being honest so please go easy on me here. 
I’ve just selected the gate on MSFS when in free flight .. ie  Departure EGLL Gate 503 and arrival EGPH Gate 6

use the EFB to import simbrief flight plan for ILS 

 

If I’m doing it all wrong, apologies. Just loving it currently and would like more features, such as VDGS.

I've downloaded EGLL Premium and added the Premium GSX profile but I cannot get the VDGS to work. Any suggestions? 
I've uninstalled and reinstalled both EGLL and GSX profile.
