Replacing telegram for notifications

Ok telegram is completely blocked of in Russia so looking for a replacement. There are a lot around but couldn’t find the one which will allow me

  1. Have notifications on android device
  2. Have several channels (priority low, medium, high) and SEPARATE settings for this channels. So i could receive notifications from all the channels and low will not notify but i can open and read while high will notify via sound and pop up. At the same time would subscribe family members to only high priority ones

So any good options here?
