If I want to give clients access to SquidHub, do they gave to sign up for an account too? Can you please clarify how we can let or clients access projects in SquidHub?

I read the FAQ that says "Clients/guests/external members will join on the free plan which gives them access to join 2 groups and use the basic features.

If clients need to join more groups (or would like access to Premium features), then they can of course decide to upgrade themselves.'

But I guess I'm still kinda scratching my head.

Thanks
