I am writing an essay in APA 7th. And the DOIs in bibliography should be linkable as following example showed by Zotero:

However, the DOIs link is not active in my bibliography:

I have already checked the " Adding URLs in bibliography", but it doesn't work.
Could anyone tell my how to solve this problem? Thank you.
