What to do if the Drag&Drop system doesn't work with UI Text in Unity?

Question

C++ / C#

I need to make it so that after some time the text appears and then disappears. But the bottom line is that I can't move Text from the Hierarchy to the Inspector. I checked it with other objects, everything works, but for some reason Unity refuses to work with text. Help me please. The problem seems to be useless, but I did not find anything on the Internet on this problem.
