FigJam text hyperlinks aren't exposed via the FigJam API

I created a board here to demonstrate

curl --location 'https://api.figma.com/v1/files/l9giJNba4NDJwBIl5EDD2S' \

--header 'X-Figma-Token: TOKEN'

All I get is

"name": "Elephant23",
"characters": "Elephant23",
...
"name": "Test",
"characters": "Test"

Is this expected?
