Issues with root certificate store in RStudio IDE

We have an organizational root certificate that is installed on all of our machines to provide a trust relationship with our certificates. When accessing our Package Manager via HTTPS we get an error due to the certificate not being trusted in the local RStudio IDE. This is unexpected because our browsers work as expected, but its not clear to me where the TLS root store is on the RStudio application.

Are there any documentation for TLS certificates in RStudio IDE?
