How would I turn Int 623527832412487691 to Str 623527832412487691 in JavaScript

Question

Im trying to save 623527832412487691 to my MySQL database for use in the future, the MySQL type of data is a string

userid STRING NOT NULL,

However when I retrieve the data it outputs 623527832412487700 as a Number

I have tried

`${623527832412487691}` 

but that outputs 623527832412487700 as a String

I have also tried

console.log(BigInt(623527832412487691)) 

but that outputs 623527832412487680n as a BigInt
