Enhancing Tightknit Hub Channels with Custom CTA Buttons for Private Programs

tightknit hub channel; CTA customization this is specific to running private programs (programs = channels) within your community. i feel like there is opportunity to take the tightknit hub channel to the next level and offer customization with type of buttons we can have there. for example, for our private programs would love a "Add to [private channel]" button. Assume Slack's native invite tool is off the table for this use case. thoughts? reactions?
