Share via Instagram

Hi all,
I am using social-share-plugin to share via Instagram. Everything goes well, and I can share the image and text.

My problem is: How to close the Instagram after share?

This is my code:

 SocialSharing.shareViaInstagram('text', this.photoUrl)
        .then(() => {
            this.api.apiPostRequest()
                .subscribe(
                    response => {
                        ...
                    },
                    error => console.log(error)
                );
        }).catch((error) => {
        console.error(error)
    });
