I'm getting errors every few hours that Teslemetry integration failed and access token is invalid: Config entry 'Teslemetry' for teslemetry integration could not authenticate: Invalid access token.
When I click a button to reauth/reload integration, it works for another few hours.

Describe the solution you'd like

I'd like to have a possibility to enter new access token via integration reconfiguration instead of removing current one and adding new integration instance.

This issue was caused by a server-side issue. You will be given the option to change the authentication token if it is still invalid at the time you perform a re-auth.

⚠️ Between 9:11 AM and 10:52AM UTC the Teslemetry authentication service experienced some short interruptions, which may have cause the Home Assistant integration to trigger re-authentication. I am aware of the cause and will put measures in place that should help avoid this happening in the future.
