Thank you for fast and clever response! It works properly as a single selector 
However, I have a problem using this selector within an "element-card" container containing, in addition to the link, the title, location+date and area. I paste my configuration below.
The result is that the table displays everything except the links. Any help will be appreciated.
{"_id":"OLX","startUrl":["https://www.olx.pl/nieruchomosci/dzialki/?search%5Border%5D=created_at:desc&search%5Bfilter_enum_type%5D%5B0%5D=dzialki-rolne&search%5Bfilter_float_m:from%5D=100000"],"selectors":[{"id":"pagination","parentSelectors":["_root","pagination"],"paginationType":"auto","selector":"a.css-1mi714g","type":"SelectorPagination"},{"id":"element-card","parentSelectors":["pagination"],"type":"SelectorElement","selector":"div:nth-of-type(n+10) div.css-qfzx1y","multiple":true},{"id":"title","parentSelectors":["element-card"],"type":"SelectorText","selector":"h6","multiple":false,"regex":""},{"id":"area","parentSelectors":["element-card"],"type":"SelectorText","selector":"span.css-643j0o","multiple":false,"regex":""},{"id":"location-time","parentSelectors":["element-card"],"type":"SelectorText","selector":"p.css-veheph","multiple":false,"regex":""},{"id":"link","parentSelectors":["element-card"],"type":"SelectorElementAttribute","selector":"div[data-cy=\"l-card\"] a","multiple":false,"extractAttribute":"href"}]}
