Considerations for new Microsoft Edge (Chromium-based)
To use S/MIME in Outlook on the web in the new Microsoft Edge web browser, you (or another admin) must set and configure the Microsoft Edge browser policy named ExtensionInstallForcelist to install the Microsoft S/MIME extension in the new Microsoft Edge. The policy value is maafgiompdekodanheihhgilkjchcakm;https://outlook.office.com/owa/SmimeCrxUpdate.ashx. And note that applying this policy requires domain-joined or Azure AD-joined devices, so using S/MIME in the new Microsoft Edge browser effectively requires domain-joined or Azure AD-joined devices.
For details about the ExtensionInstallForcelist policy, see ExtensionInstallForcelist.
This step is a prerequisite for using new Microsoft Edge; it does not replace the S/MIME control that's installed by users. Users are prompted to download and install the S/MIME control in Outlook on the web during their first use of S/MIME. Or, users can proactively go to S/MIME in their Outlook on the web settings to get the download link for the control.
Considerations for Chrome
Microsoft Edge Office 365

The policy value is maafgiompdekodanheihhgilkjchcakm;https://outlook.office.com/owa/SmimeCrxUpdate.ashx. And note that applying this policy requires domain-joined computers, so using S/MIME in Chrome effectively requires domain-joined computers.
