In the new react UI, there are problems with email connectors:
When creating a new email connection, if it's a

send email

, then the

Validate

button does not get enabled and is impossible to click, making it impossible to finish connection creation.
When creating a

receive email

connection, during the validation an empty red rectangle is drawn, and validation also gets failed.

Expected behavior

[!-- Describe what the desired behavior would be, enlisting the acceptance criteria. --]
It's possible to both validate and create both types of email connections.
