About getting Temporary STAMP4 while waiting on EU3 decision

[adublin]

Hello All,
Actually, my EU3 application is 5 weeks old now, no letter yet but my GNIB card expiring 4th April. Inis website says I'm entitled to get 6 months temporary STAMP4 while wating on EU3 decision to be made.
Now I'm wondering should I contact EU treaty section to issue me a letter for temporary GNIB card or I'll wait until they eventually reply or else I'm confused what should I do now to extend GNIB temporarily at this point.

I wish any kind reply soon and I'm grateful for any suggestion or idea anyone here might have for me.
Kind Regards.
