Vehicle set at GUI, Token renew questions

[Merwases]

As the expiration of the Stellantis Tokens from time to time isn't nice, I decided yesterday to switch from yaml config to GUI concerning vehicles and some other settings.
I'm talking here strictly about Evcc Addon used at HA System (Raspi)

Now my questions:
1.
Expired Tokens could be very easy renewed by HA "Token Helper" Addon and put the new ones into evcc.yaml.
But this way often expired.
Will GUI / db way solve this ?
2.
As I read, if vehicles are set using the GUI, the data and Tokens are stored at thd evcc.db.
As far as I read, this kind of db storage is automatically renewed by Evcc always, if the Tokens may expire.
Is this the case ?
3.
As the db isn't that easy to change by its content if may be Token gives any problem as its used by the yaml config, I find out the much more difficult way by save the date via Evcc Configuration (working only using a PC/Laptop !), open it with "DB Browser for SQLite" (PC Programm !) and (not tried, just read about) delete the Tokens or overwrite it with NULL.
Save and use this db by restore backup at Evcc.
Is the any faster/easier/better way to reset the Tokens (or delete / overwrite it at the GUI) ?
4.
I also tried to use commands via "Advanced SSH & Web Terminal" HA Addon.
Despite disabeling the security setting, most commands don't worl by saying its db case and not possible.
Stopping Evcc to avoid 2. access to db (said its not possible, just 1 time access okay), nothing works about commands at all.
Isn't it possibld at all to access Evcv by commands if set up by GUI /db use ?

Next 2 Screens show 2 places in db where the Tokens are stored:

The key place shows different Tokens, just the configs place shows the Tokens ehich have been set during configuratiln by GUI.
How does this be explained ?

Couldn't finde any real info about it, just clustered stuff at the web.
So any info welcome.
