Mouse button click from the pageObject ('mouseButtonClick' of undefined)

[Pieras2]

Code example which worked, now on NW 1.78 doesn't (mySelector is just to point about some selector).
I get "TypeError: Cannot read property 'mouseButtonClick' of undefined" ... any idea?

Verbose told me only " → Running command: perform ([Function])
unhandledRejection: Cannot read property 'mouseButtonClick' of undefined
"

        const rightButton = 2; // number of button from (0, 1, 2)
        return this
            .click('@mySelector')
            .waitForElementVisible('@mySelector')
            .click('@mySelector')
            .api.mouseButtonClick(rightButton)
            .waitForElementVisible(mySelector)
            .click(mySelector);
    },```

For now will try to workaround it.

Ok solved

    set_reset_top(selector): Promise<myPageObject> {
        const rightButton = 2; // number of button from (0, 1, 2)
        return new Promise(async(resolve) => {
            await this.click('@mySelector');
            await this.waitForElementVisible('@mySelector');
            await this.click('@mySelector');
            await this.api.mouseButtonClick(rightButton);
            await this.waitForElementVisible(mySelector);
            await this.click(mySelector);
            resolve(this);
        });
    },
