The problem of WeChat Mini Programs template message push

when Mini Program sends template messages to obtain access_token, appsecret, needs to be passed in the API parameters, but what we are doing is a third-party platform for saas service. How can we get the merchant"s appsecret? Can merchants get appsecret when they authorize our third-party platform?
