Can't find move last / first sheet navigation button in Calc vrs. 5+

In version 4.x there use to be in the left corner 4 navigation buttons, move to 1st / last sheed and next/previous sheet. In verstion 5.x can’t find/set the 1st/last sheet navigation. Since i work with docs that have 100+ sheets it is very hard to navigate one by one.
Will this change be permanent in 5.x or it will be reverted in the future?

Hi

The 5.0 introduced this: Previous and Next assume the functions of First and Last when pressing the Ctrl key while clicking.

And It is now possible to scroll the sheet tabs with the mouse wheel if the number of tabs overflows the bar’s space.

In both cases this is only active if all tabs are not visible.

(see
release notes & tdf#59471)
