Why do friends with few followers who ask for my support not come to the group and help people with their knowledge?

Come on, first show your quality, guide people, right now even though the group is small, a core audience is forming inside.
Show your quality, then as long as you help people in the group, you can also share your X accounts and content in the group and ask for support.
People you are already helpful to will support you and follow you.
If I started from zero and saw something like this, I would jump right in and prove myself inside, earning respect.
First, be useful to people and see the opportunities.
My door is open to anyone who trusts themselves, go ahead.
