Invest-api-csharp sample не работает

Склонил репозиторий. Ввёл токен как в документации вместо <token>:

cd Tinkoff.InvestApi.Sample
dotnet user-secrets set "AccessToken" "<token>"

$ dotnet user-secrets set "AccessToken" "my_sandbox_token"
Successfully saved AccessToken = my_sandbox_token to the secret store.
