how the vendors can link there accounts on Dokan plugin to add there products !!

hello,

I see the video on https://www.youtube.com/watch?v=jr2dW2Tdb-Y about connecting the plugin using WooCommerce REST API setting.
what I understand is, I should create a key for each vendor to link there account with the aliexpress Dropshipping!
also you didn’t explain how to make to edit or revoke the APIs from woocommerce setting!!

there is no explain about how to do it at all!
1- what is the key I should copy and paste it on the chrome extension as a “vendor” not admin (is it Consumer Key or the Consumer secret)!? ‘first photo’ “if it’s correct!”.
2- if so, should I create the key by the admin or the vendor user email?!
3- if so, should the vendor do it on there devices or should I do it on my device as new domain?!

note: I connect my admin account by the secret key on the main plugin general page and it’s linked perfectly and the imported products showing on my vendor account because it’s admin account also. now I don’t know how to connect the vendor account who is not an admin!

please explain it more ASAP! Thanks
