Just make sure you get a lounge invite from check in and it should be fine. I will be doing that in a couple of weeks at OSL too. Just to note I did go through in February and half the lounge was closed for refurb so it was almost impossible to get a seat. They said it would be at least 2 months until it was fully reopened so things could be slightly different with capacity restrictions now the summer timetables are just kicking in.

Please let me know how you get on and how if the lounge is fully open just so I can set my expectations for my trip.

Don’t suppose you are on the 1605 departure? Any chance you could take a pic of the menu and upload on the meal thread or just DM me.

TIA.
