Tezspire and phlegm/mucus experiences

Im getting tezspire next week and my question was; what can I expect with it? My asthma is eosinophilic and my main symptom is loads of phlegm and asthma attacks. Im reading on google that tezspire is very helpful with mucus plugs blocking the production of phlegm and mucus, but is it really? I need real life experiences.
