Hi,
no big deal.
Check FCL.625 for the IR and FCL.740.
Basically as you are current on on a pilot licence issued by a third country in accordance with Annex 1 to the Chicago Convention You have no issues, when possibile You will do Your proficiency check with no additional training. It could be in 10 years, as long as you keep current on your other ICAO licence you are good.
