VK API Why do I get error 15, access denied to call this method on wall.post method?

Hello
There is a problem when sending a post to the user's wall from the server
. I form a link to the entrance through VK through Implicit Flow in this way:
https://oauth.vk.com/authorize?client_id=0&display... In
the scope I specify the rights to wall and offline
As a result, on the server I get an access token with expire = 0, that is, a permanent token.
But when I try to make a post on the wall from the server, I get an error
{"error":{"error_code":15,"error_msg":"Access denied: no access to call this method","request_params":[{"key":"oauth","value":"1"},{"key":"method","value":"wall.post"},{" key":"owner_id","value":"0"},{"key":"message","value":"Test"},{"key":"v","value":"5.80"}]}
}
https://api.vk.com/method/wall.post?owner_id=0&mes...
Please tell me what's wrong?
