Zoom has created a higher quality recording setting option for podcasters by introducing Zoom High Fidelity Audio. According to Zoom:

"This option in Advanced Audio enhances Original Audio mode, allowing for disabling echo cancellation & post-processing, while raising audio codec quality to 48Khz, 96Kbps mono/192kbps stereo for professional audio transmission in music education and performance applications."

You can enable this setting by following the following steps.

Hovering your mouse near the bottom left of your Zoom window, click on the ^ symbol by the microphone icon, then select Audio Settings.

Open Audio Settings once again. Now, select Recording and "Record a separate audio file for each participant." This will enable you to edit each speaker's audio separately.
