need to set GITHUB_TOKEN in brownie but don't know how

[scinftist]

I'm using VPN to connect to the internet (because GitHub is not accessible in my country)

when I run > brownie compile
I get

 ConnectionError: Status 404 when getting package versions from Github: 'Not Found'

Missing or forbidden.
If this issue persists, generate a Github API token and store it as the environment variable `GITHUB_TOKEN`:

I think it caused by github rejecting my connection

I've tried to set github_token in dotenv like this:

export GITHUB_TOKEN = 'ghp_00000000000000000000000000000000000000'
also
but getting the same error
also echo $GITHUB_TOKEN
[is blank]

in the brownie docs: https://eth-brownie.readthedocs.io/_/downloads/en/stable/pdf/ page 33 installing from GitHub said :

It is possible to install from a private Github repository using an API access token like a personal access token. This can be provided to Brownie via the GITHUB_TOKEN environment variable in the form of username:ghp_token_secret. See also https://docs.github.com/en/rest/overview/

but I don't know what to do in .env or brownie-config.yaml
thank you in advance

Could you make this a question on stack exchange ETH?
