Does Affine-reader work?

[MyNameIsMaxwell]

Hi!
I used self-hosted version of AFFiNE. I tried to install Affine-reader to get text from my workspace documents, but every time I got the error at step #2:

"The name "affine-exporter" is not recognized as the name of a cmdlet, function, script file, or executable
amma. Please check that the name is spelled correctly and that the path is present and correct, and then try again."

Steps get from https://github.com/toeverything/affine-reader and https://pengx17.vercel.app/posts/affine-exporter by @pengx17:

1. Install
   pnpm install affine-reader
2. Export a affine to markdown locally
   Usage: affine-exporter -w [workspace_id] -t [token]

How can i get data from doc? In PostgresDB text is stored as a blob. Is there any way to convert them to text if affine-reader doesn't work?

Ok, ChatGPT said that affine-reader works only for Cloud version..
