Some Questions regarding "change_methods" equivalent in near-api-js

[Wabinab]

Hi, I figured function call is NearApi::Action.call(...), but how exactly do you make one? When I try tracking it down, it seems like there's some problem with access key:

Particularly,

key = NearApi::Key.new
api.view_access_key(key)

=> {"jsonrpc"=>"2.0",
 "result"=>
  {"block_hash"=>"ARj9AriWfpfBWo5m7V6bob55Q57YUaE13SXhrkqXj3c",
   "block_height"=>86533146,
   "error"=>
    "access key ed25519:dKYi64UHPLfD4C7qUUWD3eWw1rv5GjLnTCzsNxo4W6Z does not exist while viewing",
   "logs"=>[]},
 "id"=>"dontcare"}

have an error.

That is, I assume the public key is the "Hash" from the Explorer, but am I correct about that? If not, how do I get the key?

And is there a login function to login with wallet for this?

Thanks in advance.

the function call is supposed to be signed with private key (keypair)
