Emergency contact

I work in PP doing telehealth and recently had a client disclose SI to me. There must have been a glitch in the EHR and the emergency contact form was not included in the intake paperwork. I have been seeing the client for months and didn’t catch it. Now I’m kicking myself because I don’t want to spook the client (who was very leery about telling me) but I feel uncomfortable continuing without it. How should I bring this up?

Of note, client was also very resistant in the beginning due to a bad experience in therapy. I finally feel like I’ve earned their trust and some of the walls have come down.
