Research direction

The issue requests adding a web flasher by integrating esp web tools (https://esphome.github.io/esp web tools/). The contributor should investigate how esp web tools works and how to incorporate it into the WiFiManager project. They should examine the existing captive portal implementation to add a new page or endpoint for the flasher. The repository's build system and source structure need to be understood to include any necessary static files.
