Is your feature request related to a problem? Please describe.
Currently, when codes are expired and switched to the next codes, there's a short pause (about 1 second), I assume that's for calculating new codes.
All the other 2fa apps I used, including web apps, switch to the new codes instantly, some apps, such as ente auth, even display the next code along with current one.
The next code is not a secret, it's just the one that's calculated from the current expiring timestamp.
Describe the solution you'd like
Pre-caculate the next code before the current one expires (e.g. 10 seconds before), so that when the app needs to switch to the next code it's already available.

Describe alternatives you've considered n/a
Additional context It would be nice to be able to also optionally display the next codes along the current ones. The next codes could be smaller but should be copiable. As an example, see the picture of ente auth app at https://www.news47ell.com/blog/ente-authenticator-review-e2ee-google-authenticator-alternative
