How can I add a specific header when using the requests_all tools package?

[katy246-old]

I am using the Requests Langchain tool for the Agent to be able to send requests to an API that requires authentication. For this I need to add a header named Authorization to every request sent by the tool.

tools = load_tools(["requests_all"])   
tool = tools[0]     
if isinstance(tool, TextRequestsWrapper):
            tool.headers['Authorization'] = 'Bearer ' + token

but the tool is not TextRequestsWrapper although this is what I get from the docs, and any other type of tool doesn't seem to provide the option to set the headers. Please advie

requests_tools[0].requests_wrapper.headers.update({'header':'value'})
