Property 'openDatabase' does not exist on type 'SQLite'

I was able to create a new database on another .ts file. Then, I wish top open the same database on a different .ts file.

this.platform.ready().then(() => {

      let db = new SQLite();
      db.openDatabase({
        name: 'data.db',
        location: 'default'
      }).then(() => {
        db.executeSql('CREATE TABLE IF NOT EXISTS plants (id INT PRIMARY KEY, crop TEXT)', {}).then(() => {
        }, (err) => {
          console.error('Unable to execute sql: ', err);
        });
      }, (err) => {
        console.error('Unable to open database: ', err);
      });

    });

However, it is returning…

Property ‘openDatabase’ does not exist on type ‘SQLite’.

I am sure I have installed it since I was able to use it already. How come, openDatabase does not work?

The code you have does not look like the docs.
