Removing duplicates data from array using angular 9

Question

I have an array with below list of array as shown in image , I would like to remove the duplicates array "Qualif" and "Prod"

what i have

I want to be like that

what i want

I have tried with the following conditions

Scenario1 :

   this.Default_data_historique=Object.values(this.nouveau_data_historique.reduce((c,e)=>{
            if (!c[e.PTF_NAME]) c[e.PTF_NAME] =e; return c; },{}));

Scenario2 :

this.Default_data_historique= Array.from(new Set(this.nouveau_data_historique))

Scenario3 :

this.Default_data_historique=this.nouveau_data_historique.filter(function(elem,index,self){
          return index === self.indexOf(elem)
        });

None of the three scenarios above were able to remove the duplicates from that array. Could any one please help on this ?

Edit: sample data i have

[
    [{
            "PTF_NAME": "integration",
            "Salle": "salle1"
        },
        {
            "PTF_NAME": "integration",
            "Salle": "salle1"
        }
    ],
    [{
            "PTF_NAME": "Qualif",
            "Salle": "salle1"
        },
        {
            "PTF_NAME": "Qualif",
            "Salle": "salle1"
        }
    ],
    [{

            "Salle": "salle2"
        },

Try this,

data = [
    [
        {
            "PTF_NAME": "integration",
            "Salle": "salle1"
        },
        {
            "PTF_NAME": "integration",
            "Salle": "salle1"
        }
    ],
    [
      {
            "PTF_NAME": "Qualif",
            "Salle": "salle1"
      },
      {
            "PTF_NAME": "Qualif",
            "Salle": "salle1"
      }
    ],
    [
      {
            "PTF_NAME": "Qualif",
            "Salle": "salle2"
      },
      {
            "PTF_NAME": "Qualif",
            "Salle": "salle2"
      }
    ],
    [{
            "PTF_NAME": "Prod",
            "Salle": "salle1"
        },
        {
            "PTF_NAME": "Prod",
            "Salle": "salle1"
        }
    ],
    [{
            "PTF_NAME": "Prod",
            "Salle": "salle2"
      },
        {
            "PTF_NAME": "Prod",
            "Salle": "salle2"
        }
    ]
];
function removeDupesInArrayOfObject() {
  const result = [];
  result.push(this.data[0]);
  data.reduce( (first, second, n) => {
      if (first[0].PTF_NAME !== second[0].PTF_NAME) {
          result.push(second);
      }
      return second
  })
  console.log(result);
}
removeDupesInArrayOfObject();

i don't know why but done , see the link of image few arrays
,i try the new answer but nope sorry same result of my first image
Maybe you don't understand my question , i want the result like the second image , i want to remove the second array of "Qualif" and "Prod" check again what i have and what i want.
i try the new answer and i have just one array and one item for "integration"

You can use filter() method.

this.nouveau_data_historique.filter((item,index) => {
  return this.nouveau_data_historique.indexOf(item) === index
 });
