How to add a button with a link?

[olgabot]

Forgive the naive question, I am extremely new to web programming. We'd like to add a feedback button, but this code:

                html.Button('Submit feedback!', className='three columns',
                            href='https://github.com/czbiohub/singlecell-dash/issues/new'),

Produces the error that href is not a valid property:

Traceback (most recent call last):

    cli()

What's the correct way to add a button with a link?

Maybe not perfect, but works:

html.A(html.Button('Submit feedback!', className='three columns'),
    href='https://github.com/czbiohub/singlecell-dash/issues/new')
),

For some reason the links is not working. I can open it with right-click and Open in new tab. But when I just click on the button, nothing happens.

html.A(html.Button('Show API schema'), href='/api/schema/swagger-ui/', target="_blank"),

Seems the target is breaking it.
