Looking for 10 or more workspaces to install a Slack app

Hi folks,

Does anybody have test workspaces in Slack?

I have created a Slack app (https://remozoai.com), and while submitting it for review, Slack asked me to install it on 10 workspaces before they could review it. I was wondering if the community here could please help me out, please. I would really appreciate the gesture and your feedback.
