Can't add a member to board

[Phantomea]

Hello I have and issue with adding new member to board.

I can get board which I want, can use i.e. ->setLabelNames() but can't use setMemberships();

Is this function "that" function what I need to add new member to the board?

I used exactly this code
$currentBoard->setMemberships([ 'idMembership' => 'id of member', 'type' => 'normal' ])->save();

Please help me :( I really need it to finish my work.

Oukey, I'm gonna answer myself, hope someone will need to use this and it will be useful.

This is how I did it:

1. I get all my boards. $boards = $client->members()->boards()->all('me');
2. By foreach loop I found the board I wanted foreach($boards as $board)
3. Then I invited a user by his trello email: $client->boards()->members()->invite($board['id'], 'email of trello user', 'Full name of the person');
