If 2NT is natural, pass is normal.
If 2NT is clubs and/or minors, a 3♣ cue would be in order.
So pass and call director later if RHO ends up with minor(s).
If 2N is natural (and who has ever played that: don't all good players start with double of the weak 1N when holding a balanced 20 count?), then pass is silly: you have them going for their lives: double! Besides, they cannot hold 20 hcp: your hand tells you that and no committee is going to credit any assertion by you that you thought that was what might be happening.
Double may smoke out RHO (LHO is confused and will be relieved to be able to pass... altho not without running a risk) and RHO will be in a pickle: can RHO run based on the table action telling him/her that partner has no idea what was intended?
Even if there was no agreement, the fact that LHO seems to have clearly considered alerting and then passed might create an issue.
Anyway, that is not your problem. Either you defend 2N doubled or you cue whichever minor RHO bids (after calling the director... if you intend to call, call before you bid)
Passing and then calling is wrong. It is entirely possible that RHO took a chance by making a bid knowing that they had no agreement. If that is so, then you are not entitled to relief if LHO passes and they go down 8 tricks (400) against your 680 or 1430. The opps do not get penalized for making bids with no agreement.
