Account workers
When an account is authorized in Steam and on the marketplaces, you can see if it has been linked to a worker.
A Worker is a process under the hood of a service that deals with trading on a Marketplace
To go to the worker information section, click "Show Workers"
In this case, all accounts have a worker id and all accounts have a checkmark that workers work.
Also in this section you can enable or disable the sale of items on certain sites for certain accounts, if required (1, 2, 3).
To automatically accept purchases (from any marketplaces), there is an option (4) "Accept gift trades"
Once an account is added, the options to sell on all marketplaces are enabled automatically
Items will be put up for sale and start competing as soon as the minimum and maximum price limits are set! (Description of limits setting process))
