Unable to destroy session/logout in Rails - ruby-on-rails

Question

I am trying to learn Rails API with React front end and have created a login, signup and logout feature. Currently, I am using localstorage to check if a user is signed in or registered. If the value is true, the logout button appears, and clicking logout empties the localstorage and sets the value to false. But I think this isn't the correct way of doing it since rails devise has its own session and logout endpoint. I tried writing some code for the destroy session and when testing it using the endpoint in POSTMAN it doesn't seem to work the way I want.
Here's the code:
class API::V1::SessionsController < Devise::SessionsController
def create
#user = User.find_by_email(user_params[:email])
if #user && #user.valid_password?(user_params[:password])
session[:user_id]=#user.id
sign_in :user, #user
render json: #user
elsif #user && not(#user.valid_password?(user_params[:password]))
invalid_attempt
else
no_user
end
end
def destroy
puts "logout clicked"
#user = User.find_by_email(user_params[:email])
if #user.valid_password(user_params[:password]) && #user.destroy
render :json => { success: "user was successfully deleted" }, :status => 201
else
render :json => { error: "user could not be deleted" }, :status => 422
end
end
private
def no_user
render json: {error: "An account with this email doesn't exist. Please create a new one"}, status: :unprocessable_entity
end
def invalid_attempt
render json: { error: "Your password isn't correct" }, status: :unprocessable_entity
end
def user_params
params.require(:user).permit(:email, :password)
end
end
http://localhost:3000/users/sign_out
{
"user":{
"email":"test1#test.com",
"password":"test1#test.com"
}
}
Please note that this user does exist. Sending a delete request to http://localhost:3000/users/sign_out isn't even logging the "logout clicked" and the status gives 204.
