I signed up for the BETA of Options+, and I think I found a bug whereas it doesn't allow for button customization of the MX 3 Master for Webex. I'm hoping to have the same Mute/Unmute & Start/Stop Video shortcuts assigned to the side buttons as I enjoy in MS Teams, but to no avail. First the actions are not listed at all for these, but yet even entering the CTRL-M and SHIFT-CTRL-V keyboard combinations have no effect either. A post of Reddit seems to suggest it should work, but it references the non-beta Options app. Thanks in advance for your assistance.
