Vintage Platinum Zo-Gan Inlay Repair

[Lomi]

Today I received a new pen and found out a few problems that possible can be resolved by myself, though i still have a question.
The problem is silver colored inlay in pen that Nakaya refers to as "zo-gan" and it's front kinda glued out from pen body, i'm worried that any kind of force applied in opposite direction to this inlay and it can tear off, but i can lift it a little with needle and reach up to the center of it to glue it back, but i have no idea what kind of glue can be used for this kind of application, anyone had similar experience? or maybe you can recommend glue that would be safe to use and easy to remove excess from plastic, because even if reach under inlay there still a chance that some of the glue will left around that i need to remove, though please do not use any brand names and recommend just the "type" of glue by it's properties that can help, i'm kinda far from USA and chances of having same product here is close to 0, but i can try to find proper one if you can help me with "type" of glue.
From what material this inlay is made out of i have no idea, but it's possibly same white gold (WG) from which Nakaya makes their zo-gan inlays even today.

well seems like the best solution i could find is to use epoxy glue, at least that's the stuff people use to glue inlaid gold nibs back (assuming that my inlay is white gold or some kind of metal too), it's should be safe for plastic + I will have time to remove excess glue, the only thing left to do is to buy few products and do some test runs with them. Still not sure tho if I will need to clean the joint under it before using, it's hard even to see whats in there, part of this inlay is still seems securely glued and idk if it's the best idea to remove it completly, maybe it will break, but i guess i will figure out it in the process...
Unless someone could give me better ideas on what to do, i guess i will stick out to this process and will report back when I either fail or succeed, maybe it will at least help someone in the future.
