Still have the same error with specifying --share=/tmp. Maybe I should add something else?
```
kovalev@mirage ~$ guix shell --container --network --preserve="^DISPLAY$" --no-cwd --share=/tmp ungoogled-chromium -- chromium
Authorization required, but no authorization protocol specified

```
```
kovalev@mirage ~$ guix shell --container --network --preserve="^DISPLAY$" --no-cwd --share=/tmp icecat -- icecat
