我昨天安装了octavesnap，但是当我运行时octave，它没有权限访问我的$HOME. 如何启用权限？

阅读https://docs.snapcraft.io/interface-management后，我认为这会起作用：
sudo snap connect octave:home :home
error: cannot resolve connection, slot snap name is empty

description: |
GNU Octave is a high-level interpreted language, primarily intended for
numerical computations. It provides capabilities for the numerical
solution of linear and nonlinear problems, and for performing other
numerical experiments. It also provides extensive graphics capabilities
for data visualization and manipulation. Octave is normally used through
its interactive command line interface, but it can also be used to write
non-interactive programs. The Octave language is quite similar to
Matlab so that most programs are easily portable.
