Issue with sdk.start() in Signoz and Next.js

Hi Guys, I'm new on signoz, I'm trying to use signoz in next.js 13,

File: tracing.js
sdk.start()
.then(() => console.log('Tracing initialized'))
^

TypeError: Cannot read properties of undefined (reading 'then')

at node:internal/main/run_main_module:23:47

Node.js v18.14.2

I've tried debbuging this on console, which resulted that, sdk.start() was undefined

Please let me know how to fix this

Sdk.start doesn’t return a promise anymore, docs are outdated

> Then is not a promise anymore, docs are outdated
