Autocomplete in .MDX files using VScode

When I import something from .js or .ts files in .mdx files I would like to see autocomplete suggestions from VScode.

Also when I define variable inside .mdx file, I'm waiting that VScode will suggest me this variable's name.

// for example
const myVar = 'myVarValue';

<Meta title={myV /* In this moment VScode should show me suggestion */} />

Questions:

• Is it possible at all?
• If not then why and when it will be possible?
• If yes then what should I do with my VScode to it became work as I expect?
