Can I operate many accounts with just one API ID & HASH?

Description

I want to be able to operate many accounts with just one API ID & HASH.

For example, I use the API ID of A phone number to get a client, and I want to use this client to manipulate B phone number join channel or send message.

If possible, can you tell me how to do it, because I see that almost all apis are called through the client rather than the phone number.If not, should each user have their own api id？

Thanks.

You can reuse app hash and app id between multiple instances, yes.
For example, telegram desktop has a single id-hash pair that is reused between all clients.

I got it, does that mean that if I want to operate multiple accounts on just one device, even with a single id-hash, I must have to run multiple new client because each account needs an instance？
