/**
 * Please, remember that you must answer to this type of queries using something like
 * [dev.inmo.tgbotapi.extensions.api.answers.payments.answerPreCheckoutQueryOk] or
 * [dev.inmo.tgbotapi.extensions.api.answers.payments.answerPreCheckoutQueryError]
 *
 * @param initialFilter This filter will be called to remove unnecessary data BEFORE [scenarioReceiver] call
 * @param subcontextUpdatesFilter This filter will be applied to each update inside of [scenarioReceiver]. For example,
 * this filter will be used if you will call [dev.inmo.tgbotapi.extensions.behaviour_builder.expectations.waitContentMessage].
 * Use [dev.inmo.tgbotapi.extensions.behaviour_builder.BehaviourContextAndTwoTypesReceiver] function to create your own.
 * Use [dev.inmo.tgbotapi.extensions.behaviour_builder.utils.plus] or [dev.inmo.tgbotapi.extensions.behaviour_builder.utils.times]
 * to combinate several filters
 * @param [markerFactory] **Pass null to handle requests fully parallel**. Will be used to identify different "stream".
 * [scenarioReceiver] will be called synchronously in one "stream". Output of [markerFactory] will be used as a key for
 * "stream"
 * @param scenarioReceiver Main callback which will be used to handle incoming data if [initialFilter] will pass that
 * data
