In 1.16.2 Mojang has finally deemed it time to fix this issue. The mod is no longer needed if you play on 1.16.2 or higher.
Unless you are playing in creative. Where tab will focus the creative search instead: https://bugs.mojang.com/browse/MC-209155
This is a small Client Side mod that allows you to use Tab for Opening and Closing your inventory.
Somewhat of a fix for https://bugs.mojang.com/browse/MC-145691
