These fields are a summary of the Account you've set up earlier.
Fields of interest here are:
Use the settings here to set up a recurring job which will pull all changes happening inside the associated NetSuite account, and open a new pull request to the branch configured above with the changes.
On the Scope subtab, you can narrow down the scope of the scheduled sync by specifying which object groups you'd like to look out for, whether SuiteScripts should be included and what Settings/Preference types.
You can select all for each type to pull everything.
NB: We intentionally omit Saved Searches from the initial baseline in the Setup Wizard, this is because they tend to be large in size and not usually relevant for version control. You could enable them just the same in the scope.
The Git Settings subtab contains settings for controlling how the scheduled sync should interact with Git in terms of whether the Pull Request should be automatically merged, what squash commit message should be used, and whether to decode zipped objects like saved searches, report definitions and the like.
