No id on a login button in a website form - how to manage to auto logon?

Hi Team,

I am sys admin and brand new registered here but have been reading you for a long time and using your wonderful tool which has made my life easier and more productive for several years.
Thank you for your unfailing availability here and for your help which has been invaluable to me on several occasions.

I have a pretty basic concern I think only for my "comfort", but I'm sure you could help me to find the solution :)

I can log into almost any site very easily using the HTML control IDs.

But here, we have a problem Houston, the Connect button of the website has no "id" in its form.
So I have to click on the button to confirm the connection of it which then works but I would like that it log itself.

To be more precise, I give you directly the concerned site that you can see & eventually test/try on your end:
https://sso.vectorworks.net/accounts/login/

I hope there is a way / workaround without having to go through a macro for example...

Thank you very much in advance for your support.

And sorry for my 1st (from beginner of course) question.

Cheers,
Kévin
