What is the correct path to import useSSRContext in a ts file?

[penny70463]

I am working on rewriting js file into ts file in a Vue3 SSR project,
I import useSSRContext in js file by using "import { useSSRContext } from 'vue';" which was work.
But when it comes to ts file I got
"error TS2305: Module '"..../node_modules/vue/dist/vue"' has no exported member 'useSSRContext'."

I had tried " from '@vue/...' " still couldn't figure out.
Please give some hints, thanks!
