Steps to Reproduce
Steps to reproduce the behavior:

1. use create() code
2. add a function called start:

async function start(bot) {
  let groups = [];
  try {
    groups = await bot.getAllGroups();
  } catch (e) {
    console.error(e);
    return;
  }

  groups = groups.filter(({ isReadOnly }) => isReadOnly === false);
  for (const group of groups) {
    const contacts = await bot.getGroupMembers(group.id._serialized);
  }
}

create() code
This is the code you use to create the client. e.g

async function main() {
  let bot;
  try {
    bot = await sulla.create();
  } catch (e) {
    console.error(e);
    return;
  }

  try {
    await start(bot);
  } catch (e) {
    console.error(e);
  }
}

main();

Expected behavior
A list of group members would be returned.

DEBUG INFO
This is the info printed to the console when you start your app. It should look like this
