[FEATURE] utilize Android share fearuew

Describe the solution you'd like
A clear and concise description of what you want to happen.

I would like when using the share option in another app, such as a web browser, sharing to amethyst was an option

Bounty (in Bitcoin sats) offered for the implementation 10
The size of the bounty is proportional to how much this matters to you. If no bounty is offered,
not even a small one, this feature will not be coded because it doesn't actually matter to you.
We prioritize feature development by its bounty size compared to how much work is required to get it done.

Latest version of amethyst allows this.

Sharing from a browser I have "Amethyst New Post" avilable as an option.
