Token-based authentication to Azure SQL Server

I have need to authenticate to Azure SQL Server using token based authentication. This is possible in other languages like Python because the ODBC packages like pyodbc support pre-connection attributes (https://github.com/mkleehammer/pyodbc/issues/228). However, none of the R ODBC packages: RODBC (https://www.rdocumentation.org/packages/RODBC), ODBC (https://www.rdocumentation.org/packages/odbc), or r-dbi (https://www.rdocumentation.org/packages/DBI), support pre-connection attributes.

I can't use ActiveDirectoryPassword authentication because this doesn't work from Mac/Linux when the user is a guest of the tenant.

It'd be great if MS could provides means of token-based authentication to Azure SQL Server.
