Support for Solo Users in Relume's Sharing Options

Good evening from a New Zealand Relume user. I'm relatively new to Relume, with just a couple of months under my belt using Relume. My strategy so far has been to use Relume to build, tweak and play with my site design until I'm happy with it, then export to Figma ready to share with my client. Then we get feedback and tweak, then export again etc etc. Ideally I would want to use the tools for sharing in Relume, but I feel like I would need to use the branded sharing option that seems to come with the Team version of Relume. However, I am a team of 1, so I don't have any internal staff to share the load or costs with. My question is; is there any provision or any planned provision on the roadmap for folks like me who do all this stuff on their own and would love to use the internal Relume sharing mechanic, but don't have the team to support the Team version. I know I could spring for the $NZ250/month option, but that's almost 3x the cost and as a startup, I can't quite stretch to that right now (although as soon as I can I will do it anyway). Additional question; would the Team branded sharing option allow me to share using a subdomain I own, so something like clientpreview.domain.com and just have that in a framed container? Sorry for the long initial post, and keep up the good work, I wish I'd found you sooner!
