Trying to add a user persona created in Figjam in a file I'm creating in Figma

I created a user persona in Figjam and I want to put it in a screen I’m creating in Figma. I copied and pasted it but in the assets panel it remains on the canvas rather than within the frame. I’ve tried dragging it down in the assets panel and it simply won’t go. I can move it around in the assets panel on the canvas (placing it above or below other elements on the canvas) but it simply will not move it into the file for the frame I want to use it in. This is the first time I’ve used Figjam, am I missing something?
