discord.js - How to get random user ID's of users with reaction

I want to get random user ID from users with reaction on specific message.

    await msg.react("<:SenkoSad:788848057844367411>")
    setTimeout(()=> {
        const winner = msg.reactions.cache.get("<:SenkoSad:788848057844367411>").users.cache.random().id
        message.channel.send(`Random user from emotes: <@${winner}>`)
    }, time-Date.now())

Here is error: TypeError: Cannot read properties of undefined (reading 'users')
on line const winner = msg.reactions.cache.get("<:SenkoSad:788848057844367411>").users.cache.random().id

Try switching the line to:

const winner = msg.reactions.cache.get("788848057844367411").users.cache.random().id

I am not entirely sure, but perhaps get() expects a Snowflake for a custom emoji rather than the format you provided.

Try using @metro's answer but use the filter function

Like:

msg.reactions.cache.get("788848057844367411").users.cache.filter(e => !e.bot).random().id
