Installation 
Once you have completed the previous section setup on the Notion side, you can install and configure the plugin in Obsidian.
Open Obsidian's
Settings.
Navigate to
Community plugins.
TIP
If you haven't enabled community plugins before, you may need to turn off Safe mode first (Turn on Community plugins).
Go to
Community plugins->Browse.
Search for "NotionNext" and click
Install.
After installation, enable the plugin.

Now, once enabled, you can find the "Share to NotionNext" settings in the plugin settings tab to begin configuring your databases in the next step.
