Pass data to a store?

How can I pass data from my vue component into a store?

Here's my component:

methods: {
    ...mapActions('NavBar', [
        'fix',
    ]),
    onClick: function() {
        this.fix('my-data');
    },
    ....

And on the store:

actions: {           
   fix: ({ commit }) => {
    //get data here?
   },
},
