Consider the following code:

```auto
module experiment::test {
    struct TableA has key{
        id: UID,
        list: Table<String, bool>
    }

    fun init(otw: TEST, ctx: &mut TxContext) { 
       // Create TableA type Object
    }

     public entry fun add_element(
        object_id: UID,
        element_to_add: String
    ){
        // Add element to the object with the ID, object_id
    }

```

In the `add_element` function how can I access the TableA type Object and add the string element `element_to_add`?

@tahlil Set the argument to `TableA` object, not a `UID`.

```auto
    public entry fun add_elements(tableA: &mut TableA, key: String, value: bool) {
        table::add(&mut tableA.list, key, value);
    }

```
