Return the names of all objects associated with R in a Databricks Notebook

By -

My organization recently switched from running r in R-Studio to r in Azure Databricks. I relied on R-Studio's environment pane quite heavily. Is there a way to list the objects specifically associated with r in a Databricks' Notebook in a similar fashion to R-Studio's Environment Pane?

I have tried objects(), ls.str(), and ls(), all of which unfortunately return a number of objects specific to Databricks.

Does anyone know how such an error can be caused, or any ideas how it can be resolved? Thanks for your help EDIT: I just checked the A DNS record for js.authorize.net and am getting the following result only: js.authorize.net. 100 IN CNAME js.authorize.net.cdn.cloudflare.net.
