Slack Missing_scope users:read.email in OIC Slack Adapter

Summary:

Content (required):

When we add the scope "users:read.email" in the connection then it gives us an error that this scope is not supported. We were able to add "users:read" scope in the connection successfully, however, when we use the slack adapter out of the box "getUserByEmail" feature inside the integration, it throws an error:

<slackResource.definitions.users.getUserByEmail_GET._ResponseDataType>

  <ok>false</ok>

  <error xmlns="">missing_scope</error>

  <needed xmlns="">users:read.email</needed>
