In “write” mode, click on the “set variable” action. Insert your resource into it, for example, {{links_data|notreuse}}, and you will receive your links in the variable.
@yourfriendkarol Please be more specific on what you are going to achieve. Resources in BAS are very powerful but somewhat limited on the other hand. In total I spent few hours on github trying to understand if using a resource would be good for my this or other problem.
