TOTP UI Viewer

Is your feature request related to a problem? Please describe.

The user who was associated with a custom totp (example: external MFA) can only read the token value by command line (vault read) or by API.

Describe the solution you'd like

The user when entering the Web UI should be able to "generate a token" (vault read totp/code/testuser)

Describe alternatives you've considered

I would like to have a custom secret engine that allows taking the output of the "vault read $path" command as a variable.

Explain any additional use-cases

The totp is a quick and easy way to implement a secret. It would be interesting if it is easy to consume through the Web UI

vault read totp/code/testuser = to click and generate

Additional context

None
