Auto-Flash to Elite-C not working on Mac OSX Catalina

[bilzard]

Describe the Bug

Auto-flash functionality didn't worked when writing firmware to Elite-C.

System Information

• Operating system: Mac OSX Catalina (10.15.7)
• QMK Toolbox version: 0.0.21

Additional Context

If I check Auto-Flash, qmk toolbox's console outputs There are no devices available, and failed to write firmware (fig1).
However, manually pushing flash button worked (fig2).
The issue didn't reproduce in version 0.0.20 (fig3).

fig1. checked Auto-Flash on ver. 0.0.21

fig2. manually push flash button on ver. 0.0.21

fig3. checked Auto-Flash on ver. 0.0.20
