Autocompletion for Argument valid options

I’m using vim + coc for autocompletion. I have installed terraform-ls and configured coc as suggested in the docs and I’m getting autocompletion when writing resources.

However, I don’t get autocompletion for arguments that only support a limited set of values e.g the azurerm_storage_account resource and its account_tier argument which defines the Tier to use for this storage account. Valid options in this case are Standard and Premium . For BlockBlobStorage and FileStorage accounts only Premium is valid.

Does terraform-ls support that use case? what coc settings I might be missing if it does?

thanks in advance
