Change/Add keyboard language in Teams for Windows 7

Hi there! I have the Teams application installed on my company's Windows 7 Enterprise 64bit machine and I would like to know if there's a way to add my native language to the keyboard settings in Teams. My laptop and all applications, including Teams, are in US English display language, but my keyboard settings are in Portuguese-PT for everything, except for Teams, which I can't change to it, as it is absent in its settings.

Thanks!
