How do I wait for a Collector to finish before executing lines below?

let comArr = [`slice`, `call`, `walk`];
            let actionVal = 0;

            await msg.edit({ ephemeral: false, embeds: [embed], components: [buttonArr] });

            let filter = m => comArr.includes(m.customId) && m.user.id == message.author.id;
            let collector = await message.channel.createMessageComponentCollector({ componentType: Discord.ComponentType.Button, filter, time: 15000 });

            collector.on('collect', async i => {
                await i.deferUpdate();
                await n.sleep(50);
                console.log(i.customId)
                if (i.customId == `slice`) {
                    actionVal = 1;
                    collector.emit('end', collected => { });
                } else if (i.customId == `call`) {
                    actionVal = 2;
                    collector.emit('end', collected => { });
                } else if (i.customId == `walk`) {
                    actionVal = 3;
                    collector.emit('end', collected => { });

                }

            });
