feature/discuss: ability to view (and edit?) user-generated token

[YpeZ]

Issue

Currently users are able to generate tokens for working with e.g. the Pyclient. However, after creating these tokens the user is only able to see the names of the tokens they created and can then only delete them.

Users who apply these tokens for a specific use are required to create a new one in case they forgot or lost it.

Solution

The functionality to view and edit a token should be implemented.

Additionally it would be nice to see the expiry date of the tokens.

Alternatives

No response

Additional context

I suppose it is a design choice not to make the token viewable after creation.
