How i can call function inside function

    async function Blast2(){

        const delayTime = 1000
        const timer = ms => new Promise(res => setTimeout(res, ms))

        function ClearDelayTime(){
            return clearTimeout(blast)
        }

        const blast = setTimeout(function() {
            let blast = "SELECT * FROM admin_contacts,temporary WHERE blast_status = 'sended'"
                db.query(blast, async function (err, result, field) {
                    if (err) throw err;
                
                    loop:{
                        for (var i = 0; i < result.length; i++) {
                            console.log(result[i].telefone)
                            await timer(delayTime); // then the created Promise can be awaited
                        }
                    }


                })
        }, delayTime );
    }

    Blast2().ClearDelayTime() <------ I Want Call the fucntion ClearDelayTime() inside Blast2()

I have tried this, but without success
I would like to call a function that is inside another function, that function will clear the timeout.
