I would like to add a clickable URL link in the red box of the following image. But I don't know where to edit it.
Please tell me how to add it.

Hey @Takakazu Sato :

You will need to add an anchor tag to the UI page 

< a href="<your desired link" target="_blank" > "your link display name" </a>

For more on anchor refer below

Thanks for the reply.
What line should I insert this HTML code?
It would be helpful if you could tell me.
