Add customer to a group with my custom module

[nandosendraa]

I'm trying to add a customer to a group but it doesn't work,

I have tried these two things obviously separately, but doesn't do nothing

$customer->updateGroup([4]);

$customer->addGroups([4]);

Are you sure your code is triggered?

I've tried first

$customer->updateGroup([4]);

and in other try

$customer->addGroups([4]);

But nothing works

But are you sure your code is triggered? Maybe code is never triggered that why is not working.

I comproved that th code is triggered dumping the customer variable
