Yes. There are two scenarios:
The person has an email address from an approved domain.
In that case, the person can directly create an OSlash account, join the workspace, and view the destination page.
The person does not have an email address from an approved domain.
In this case, the person would not be able to directly join the OSlash workspace. They would need to send a join request to the admin of the workspace. They would be able to view the destination page only after the join request is approved by the workspace admin.
