Android's work profile feature lets you have two copies of an app running at the same time. To activate this feature, you'll need a work profile manager app such as Insular or Shelter.

Insular (FOSS fork of Island without proprietary blobs): https://f-droid.org/en/packages/com.oasisfeng.island.fdroid/

Shelter: https://f-droid.org/en/packages/net.typeblog.shelter/

A quicker way might be to use the work profile thst modt ,odern android devices support. An easy and flexible way tomdo this is to install "island" to set it up and then clone discord into it. Only supports two setups then but it's really easy to do out of the box. Editing the apk to allow multiple installs though would then let you do more but it's also more work to do.

Parallel Space should solve that problem for you.
