How do i get my secure box back? Htc one

[AC Question]

My HTC one updated now when I long press contacts in messages no option to move to secure box!

I'm not sure since I'm not familiar with HTC anymore. I'll ask other members that are more familiar with HTC phones.

I wish there was more information about this online. I really loved this feature.
