bug: battery optimization request improper
**Describe the bug**
Cake added a feature to disable battery optimizations on android, but it never worked. 

On newer android devices, it _should_ launch a (native android) popup telling the user that cake would like to disable battery optimizations

**To Reproduce**
Steps to reproduce the behavior:
1. install cakr
2. open cake

**Expected behavior**
Expect to see a popup asking me to disable battery optimizations 

**Screenshots**
Here is an example from `another term`
