Got it. Can we remove the placeholders? Since you added labels, users will know what to type inside them.

Regarding the labels, since it's a Link Window and we're only interacting with the link (not any other functionality), users will understand that the 'Text' and 'URL' refer to the link. There's no need to specifically label them as 'Link Text' and 'Link URL'.

Also, I think it would be nice to stay consistent with Rocket.Chat channel terminology, using only 'Text' and 'URL'.

Got it!
Will commit soon.
