Its that like the final stage?
Same as for my first answer I Googled the right words, found a page called Bill stages. Information on that page explains Bill can start is either Commons or Lords, 3 readings each, then it is agreed and taken to royal assent.
When I looked for answer to your first question I could see the Online Safety Bill has had 3 readings in the commons, it's had 2 in the lords, plus various committee stages. After third reading looks like it goes back to the Commons for final acceptance the royal assent.
All this can be found by googling Online Safety Bill, and separate search 'stages of Bill through parliament'
