Support for assuming role via Web Identity Tokens

[KoeusIss]

I need to ask how could be possible to assume a role via AWS Web Identity Token.

Assume Role With Web Identity

Environment

• Elixir & Erlang versions (elixir --version):
• ExAws version mix deps |grep ex_aws
• HTTP client version. IE for hackney do mix deps | grep hackney

Current behavior

Include code samples, errors and stacktraces if appropriate.

Expected behavior

Hey @KoeusIss as per the docs, you need to use ex_aws_sts as well.
