Hi @Anxious ,
Does the person you share the tab with need to edit the data? If not, create a view that displays only what you want to share and click the Share View button. This will create a link that you can share. The person will not be able to modify or add any records unless you have shared the entire base with them.
You cannot share two tabs from the same link, so you will need to do this for both tabs or create a tab that aggregates both tables and share that one.
