Joined an open guild

I just joined an open guild, first time joining one, and I can't see where to send heal kits nor chat.... can someone help me figure this out? I play on my phone and I have android
There's a small tab in the middle if the left side of your screen. Click that to open your guild chat.
For the heal kits click your guild hall and then the little heal kit icon.
