Hi @ksonia, thanks for your message.
As the plugin page description is a bit outdated, please follow the supporting documentation setup guidance, available here: Google Sheets + Offline Plugin - Zeroqode Documentation
Also, for your guidance, please check the plugin Demo Editor page for setup example: googlesheetsplugindemo | Bubble Editor
We will update the plugin description, to guide users straight to the relevant supporting documentation, thanks for noticing that.
Hope it helps. In case you are using another Google Sheet plugin (we have 3 of them totally) or still need any plugin-related support, please let me know, I will be glad to help
