Personal token 401 error

>Hello. I want to create a release not when I use personal token.But i got a 401 error.
```sh
gren release --data-source=milestones --milestone-match="1.0.6" --override --tags=1.0.6
```

I had saw some issue with this proberblem. also use -t [toke] to try make it ok. But It's no.
Here is my token permission.
There has any way to solve it? Thanks a lot.

Start by reproducing the reported `gren release` command with the documented `-t` token option and inspect how the command authenticates with GitHub. Compare the token permissions shown in the issue with the API request that returns 401; done means identifying the authentication mismatch and confirming that release creation succeeds.
