I want to access varible userinfo from flask route chat or from flask main to the GetIncidentsByUserTool which was present outside of the flask instance without specifiyng the global varibale i want to access

I have tried this way
def init(self, userinfo):
self.userinfo = userinfo

but I am getting error`
