Client workspce plan

Hi everyone, I hope y’all doing great, I had this question for a while already, I have this client that I’m going to make a website for on Webflow, he doesn’t have a workspace plan, he’s only going to buy a hosting plan once the website is ready, if he invites me now as a guest on HIS worksapce (I have the freelacer plan), will I be able to work on his basic plan as a guest normally and embed code or he has to upgrade his workspace so I can do that.
Thanks in advance
