Try to automate u2f authentication, with vendor-specific implementations of what 'authenticate_u2f' would be.

bufferedAmount
The bufferedAmount attribute must return the number of bytes of application
data (UTF-8 text and binary data) that have been queued using send() but that,
as of the last time the event loop started executing a task, had not yet been
transmitted to the network. (This thus includes any text sent during the
execution of the current task, regardless of whether the user agent is able
to transmit text asynchronously with script execution.) This does not include
framing overhead incurred by the protocol, or buffering done by the operating
system or network hardware. If the channel is closed, this attribute's value
will only increase with each call to the send() method (the attribute does not
reset to zero once the channel closes).
