.gitignore not working when committing to repo

Hi,

We have recently come across the developer mode. We're looking to use it for our team so mutiple team members can work within one dashboard stored on a repo.

We are using direct query to databricks as the data source. The credentials for which store in the model.bim file. As this is sensitive data, we don't want to include the model.bim file in any commits, with the access details to the data being held within the team.

When the model.bim file is added to the git.ignore, and a data change is made to the underlying data therefore changing the model.bim file, this change is picked up and commited.

Is there a trick we're missing in adding the model.bim file to gitignore and it working?
