Hikamarket Front End - Adding Users to a Store

-- HikaShop version -- : 6.3.0
-- HikaMarket version -- : 6.0.0
-- Joomla version -- : 5.4.2

Hello

I'm testing the creation of sellers from the Hikamarket front end. When accessing the Store Administration Panel and editing the seller account, the option to add users to manage the store and assign them different permissions is available.
I've attached a screenshot.

I added a user to a seller account, but when they log in, they can't access the seller panel for that account. They log in as a regular registered user, and if I type the seller panel URL in the address bar, I get an error message indicating that I don't have permission. I've attached a screenshot.

Can you explain how to configure this functionality?

Thank you
