If it is really a supervisor, then this is the backstage establishment of the company.
However, many insurance companies need to take an agent's license for supervision and group training, but they can't have an exhibition license like business people. Take the exam if you want. Don't think that you must be a salesman as long as you pass the agent exam.
In addition, supervision and group training may take 1~2 months to get familiar with the market and the working life of salesmen, but during this period, there is a basic salary (basic salary), not an "allowance"-this is the fundamental difference from the field.
