missing permissions in list - node.js

Question

for the command to work it needs 3 permissions, but how could I reduce its size and simplify it for it to identify the missing ones and send a list, and not go from one in one?
e.g.
list = {
USE_EXTERNAL_EMOJIS: 'use external emojis',
EMBED_LINKS: 'embed links',
READ_MESSAGE_HISTORY: 'read message history'
}
CODE:
if (!message.channel.permissionsFor(client.user).has('USE_EXTERNAL_EMOJIS' && 'EMBED_LINKS')) {
return message.channel.send('missing permissions use external emojis and embed links');
}
if (!message.channel.permissionsFor(client.user).has('EMBED_LINKS')) {
return message.channel.send('missing permission embed links');
}
if (!message.channel.permissionsFor(client.user).has('USE_EXTERNAL_EMOJIS')) {
return message.message.channel.send('missing permission use external emojis');
}
if (!message.channel.permissionsFor(client.user).has('READ_MESSAGE_HISTORY')) {
return message.channel.send('missing permission read message history');
}

You can use Object.entries() to get an iterable array of key - value pairs and use a method like this
const neededPermsObj = {
USE_EXTERNAL_EMOJIS: 'use external emojis',
EMBED_LINKS: 'embed links',
READ_MESSAGE_HISTORY: 'read message history'
}
const missingPerms = [];
for (const [key, value] of Object.entries(neededPermsObj)) {
if (!message.channel.permissionsFor(client.user).has(key.toString())) {
missingPerms.push(`${key}: ${value}`)
}
}
if (missingPerms.length != 0) return message.channel.send(missingPerms.join('\n')); // prevent from running cmd
else // execute command code here
This would check if bot has the specified permissions from the object provided, and will return an array with all the missing permissions
