How to create your file with functions?

Question

JavaScript

In general, I’m not good at browsing the Internet, apparently, I’ve surfed all over, but I didn’t find what I needed.
I managed to do what I wanted, but not completely.
What I have:

//в main.js
bot.func = require('./functions'); //должно писаться именно так, ибо переменная бот летает по всему коду. 

//в /functions/index.js
function getMemoryMember (bot, id) {
   //1412351235
}
function getGuildMember (bot, id) {
     //1412351235
}
function addExp (bot, id, exp) {
     //1412351235
}
function getGuildRole (bot, id) {
    //1412351235
}
function declOfNum(n, text_forms) {  
     //1412351235
}
function getTime (time) {
     //1412351235
}

module.exports = {
    getMemoryMember: getMemoryMember,
    getGuildMember: getGuildMember,
    addExp: addExp,
    getGuildRole: getGuildRole,
    declOfNum: declOfNum,
    getTime: getTime
};

With this code, I can easily access bot.func "function name" in all files and everything is fine. But I really don't like that the bot variable is not passed here, and I have to pass it when using the function.
About what I want:

//в main.js 
bot.func = require('./functions')(bot);

//в /functions/index.js
module.exports = (bot) => {
function getMemoryMember (bot, id) {
   //1412351235
}

As I understand it, with this syntax, require itself becomes a function and cannot pass something from itself. How do I get it right so that the bot goes there with require.
ps I've already read 15 articles about functions, require, and exports =/

Well, for example, like this, if you do not change the definition of functions:

//в main.js 
bot.func = require('./functions')(bot);

//в /functions/index.js
module.exports = (bot) => ({
    getMemoryMember: (id) => getMemoryMember(bot, id),
    getGuildMember: (id) => getGuildMember(bot, id),
    ...
    declOfNum,
    getTime,
});

Although I could just add them directly to the bot and use this.

// в main.js
Object.assign(bot, require('./functions'));

// вместо bot.func.getMemoryMember(bot, id)
bot.getMemoryMember(id);

//в /functions/index.js
function getMemoryMember (id) {
   // тут использовать this вместо bot
}
function getGuildMember (id) {
     //1412351235
}
...

module.exports = {
    getMemoryMember,
    getGuildMember,
    addExp,
    getGuildRole,
    declOfNum,
    getTime
};

Or maybe you even need to add it to the bot prototype, but you already need to look at how the bot and its prototype are defined.
