Guys, I'm going to create a custom tap for kaseyaVSA. The biggest problem is that they have strange authorization. In order to get the first token, you need to encode the username and password in some way, then pass them as basic vatization in order to get the bearer token, then I must use this bearer token for all requests. When the lifetime of the bearer token ends, I need to get it again by encoding the username and password and request the bearer token. Please tell me how to implement it
