New views are personal: only you can see them. You recognise a personal view by the small person icon.
Open the view you want to share.
Click Share in the top right.
Search for a colleague and choose Full access, Can view or No access.
Optional: set General access for everyone in the environment.
Click Copy link to send the link to your colleague.
Callout: Can view means your colleague cannot change the view settings (columns, filters, grouping). It does not affect whether they can edit the documents themselves.
