How to make chrome visible to the user if selenium is running on a sever (for a webapp)?

I am building a web application where selenium fills out a form but it may require human intervention.
How do I let user intervene the driver?

Two possible ways that I can think of:

1>> Somehow, selenium on the server should be able to open chrome on the user’s desktop.

OR

2>> User should be able to see chrome running on the server

But how??

I checked if I can run selenium on colab (like a server hosting a website), I can but it has to be ‘headless’ otherwise it doesn’t work.
